Italy's vibrant capital lives in the present, but no other city on earth evokes its past so powerfully. For over 2,500 years, emperors, popes, artists, and common citizens have left their mark here. Archaeological remains from ancient Rome, art-stuffed churches, and the treasures of Vatican City vie for your attention, but Rome is also a wonderful place to practice the Italian-perfected il dolce far niente, the sweet art of idleness. Your most memorable experiences may include sitting at a caffè in the Campo de' Fiori or strolling in a beguiling piazza.

Livorno is a gritty city with a long and interesting history. In the early Middle Ages it alternately belonged to Pisa and Genoa. In 1421 Florence, seeking access to the sea, bought it. Cosimo I (1519–74) started construction of the harbor in 1571, putting Livorno on the map. After Ferdinando I de' Medici (1549–1609) proclaimed Livorno a free city, it became a haven for people suffering from religious persecution; Roman Catholics from England and Jews and Moors from Spain and Portugal, among others, settled here. The Quattro Mori (Four Moors), also known as the Monument to Ferdinando I, commemorates this. (The statue of Ferdinando I dates from 1595, the bronze Moors by Pietro Tacca from the 1620s.)In the following centuries, and particularly in the 18th, Livorno boomed as a port. In the 19th century the town drew a host of famous Britons passing through on their grand tours. Its prominence continued up to World War II, when it was heavily bombed. Much of the town's architecture, therefore, postdates the war, and it's somewhat difficult to imagine what it might have looked like before. Livorno has recovered from the war, however, as it's become a huge point of departure for container ships, as well as the only spot in Tuscany for cruise ships to dock for the day.Most of Livorno's artistic treasures date from the 17th century and aren't all that interesting unless you dote on obscure baroque artists. Livorno's most famous native artist, Amedeo Modigliani (1884–1920), was of much more recent vintage. Sadly, there's no notable work by him in his hometown.There may not be much in the way of art, but it's still worth strolling around the city. The Mercato Nuovo, which has been around since 1894, sells all sorts of fruits, vegetables, grains, meat, and fish. Outdoor markets nearby are also chock-full of local color. The presence of Camp Darby, an American military base just outside town, accounts for the availability of many American products.If you have time, Livorno is worth a stop for lunch or dinner at the very least.

Cannes is pampered with the luxurious year-round climate that has made it one of the most popular resorts in Europe. Cannes was an important sentinel site for the monks who established themselves on Île St-Honorat in the Middle Ages. Its bay served as nothing more than a fishing port until in 1834 an English aristocrat, Lord Brougham, fell in love with the site during an emergency stopover with a sick daughter. He had a home built here and returned every winter for a sun cure—a ritual quickly picked up by his peers. Between the popularity of Le Train Blue transporting wealthy passengers from Calais, and the introduction in 1936 of France's first paid holidays, Cannes became the destination, a tasteful and expensive breeding ground for the upper-upscale.Cannes has been further glamorized by the ongoing success of its annual film festival, as famous as Hollywood's Academy Awards. About the closest many of us will get to feeling like a film star is a stroll here along La Croisette, the iconic promenade that gracefully curves the wave-washed sand coastline, peppered with chic restaurants and prestigious private beaches. This is precisely the sort of place for which the French invented the verb flâner (to dawdle, saunter): strewn with palm trees and poseurs, its fancy boutiques and status-symbol grand hotels—including the Carlton, the legendary backdrop to Grace Kelly in To Catch a Thief —all vying for the custom of the Louis Vuitton set. This legend is, to many, the heart and soul of the Côte d'Azur. 

Considered Corsica’s primary commercial and cultural hub, the largest city and regional capital of Ajaccio is situated on the west coast of the island, approximately 644 km (400 miles) southeast of Marseille, France. Founded in 1492, vestiges of ancient Corsica in this ville impériale revolve around the city’s most famous son, Napoléon Bonaparte, whose family home—now the national museum Maison Bonaparte—pays tribute to the emperor’s historical influence.Remnants from what was originally a 12th-century Genoese colony are still visible around the Old Town near the imposing citadel and watchtower. Perfect for exploring, the luminous seaside city surrounded by snowcapped mountains and pretty beaches offers numerous sites, eateries, side streets, and a popular harbor, where sailboats and fishing vessels moor in the picturesque Tino Rossi port lined with well-established restaurants and cafés serving fresh local fare.

The capital of Menorca since 1721, Mahon has a impressive natural deep water harbour, which is one of the largest in the world. This, coupled with its strategic location, has made it a stronghold for many nations throughout history. Mahon has an abundance of historical buildings, the oldest being the Arch of Saint Roc which is all that remains of the wall that once encircled the whole town. The island was occupied by the British during the 18th century and Lord Nelson is thought to have stayed there. Indeed, San Antoni Mansion, located on the north side of the harbour, houses a collection of Nelson memorabilia. The legacy of colonial rule can be seen in the muted Georgian style of some of the buildings, but Mahon still boasts attractive examples of neo-Classical, Baroque and Romanesque architecture. With narrow streets to explore, pleasant shaded squares and welcoming pavement cafés, there is something for everyone to enjoy. Please be aware that most shops in town close for a siesta between 1330 and 1730.

As you sail into Malaga you will notice what an idyllic setting the city enjoys on the famous Costa del Sol. To the east of this provincial capital, the coast along the region of La Axarqua is scattered with villages, farmland and sleepy fishing hamlets - the epitome of traditional rural Spain. To the west stretches a continuous city where the razzmatazz and bustle creates a colourful contrast that is easily recognisable as the Costa del Sol. Surrounding the region, the Penibéetica Mountains provide an attractive backdrop overlooking the lower terraced slopes which yield olives and almonds. This spectacular mountain chain shelters the province from cold northerly winds, giving it a reputation as a therapeutic and exotic place in which to escape from cold northern climes. Malaga is also the gateway to many of Andalusia's enchanting historic villages, towns and cities.

The provincial capital of the Valencian Community serves as a gateway to the huge influx of tourists that flock to the Costa Blanca resorts every year. Alicante is popular with holidaymakers who arrive for the warm, Mediterranean climate and seemingly endless golden beaches. However, there is much more to this city than sand and sun. With a picturesque waterfront, a hugely impressive castle, buzzing nightlife and a rich, complex history, Alicante is a fascinating destination all year round.

The infinite variety of street life, the nooks and crannies of the medieval Barri Gòtic, the ceramic tile and stained glass of Art Nouveau facades, the art and music, the throb of street life, the food (ah, the food!)—one way or another, Barcelona will find a way to get your full attention. The capital of Catalonia is a banquet for the senses, with its beguiling mix of ancient and modern architecture, tempting cafés and markets, and sun-drenched Mediterranean beaches. A stroll along La Rambla and through waterfront Barceloneta, as well as a tour of Gaudí's majestic Sagrada Famíliaand his other unique creations, are part of a visit to Spain's second-largest city. Modern art museums and chic shops call for attention, too. Barcelona's vibe stays lively well into the night, when you can linger over regional wine and cuisine at buzzing tapas bars.

La Spezia is sometimes thought of as nothing but a large, industrialized naval port en route to the Cinque Terre and Portovenere, but it does possess some charm, and it gives you a look at a less tourist-focused part of the Riviera. Its palm-lined promenade, fertile citrus parks, renovated Liberty-style palazzos, and colorful balcony-lined streets make parts of La Spezia surprisingly beautiful. Monday through Saturday mornings, you can stroll through the fresh fish, produce, and local-cheese stalls at the outdoor market on Piazza Cavour, and on Friday take part in the busy flea market on Via Garibaldi. There's also Porto Mirabello, a newly built tourist port with a pool club, shops, and several restaurants that overlook the fleet of super-yachts.

Naples, in the Campania region, is Italy's third largest city. Its claim to fame is the spectacular location along one of the world's most splendid bays, backed by the perfect cone of Mount Vesuvius. In addition to its beautiful setting, Naples' surprises with other outstanding attractions such as the Royal Palace, San Carlos Opera House, the impressive National Archaeological Museum and the Castel Nuovo, dating from the 13th-century. The city's central area is best explored on foot. Chaotic traffic conditions make driving around the city a very frustrating experience. Naples provides a convenient starting point for trips to such favored destinations as Pompeii, Herculaneum and Mount Vesuvius. The Isle of Capri can be reached via a 45-minute hydrofoil service. The region of Campania was home to Greeks settlers some 300 years before Rome was founded. Pompeii, too, was a Greek town before being conquered by the Romans during the 5th century BC. It was under the Romans that Pompeii flourished and grew prosperous. When Mount Vesuvius erupted in 79 AD, the population of 20,000 was wiped out, but dozens of buildings were preserved under layers of cinder more than 20 feet deep. The most important finds from Pompeii are displayed in Naples' National Archaeological Museum. A visit here will no doubt enhance a visit to ancient Pompeii.

Siracusa, known to English speakers as Syracuse, is a wonder to behold. One of the great ancient capitals of Western civilization, the city was founded in 734 BC by Greek colonists from Corinth and soon grew to rival, and even surpass, Athens in splendor and power. It became the largest, wealthiest city-state in the West and a bulwark of Greek civilization. Although Siracusa lived under tyranny, rulers such as Dionysius filled their courts with Greeks of the highest cultural stature—among them the playwrights Aeschylus and Euripides, and the philosopher Plato. The Athenians, who didn't welcome Siracusa's rise, set out to conquer Sicily, but the natives outsmarted them in what was one of the greatest military campaigns in ancient history (413 BC). The city continued to prosper until it was conquered two centuries later by the Romans.Present-day Siracusa still has some of the finest examples of Baroque art and architecture; dramatic Greek and Roman ruins; and a Duomo that's the stuff of legend—a microcosm of the city's entire history in one building. The modern city also has a wonderful, lively, Baroque old town worthy of extensive exploration, as well as pleasant piazzas, outdoor cafés and bars, and a wide assortment of excellent seafood. There are essentially two areas to explore in Siracusa: the Parco Archeologico (Archaeological Zone), on the mainland; and the island of Ortygia, the ancient city first inhabited by the Greeks, which juts out into the Ionian Sea and is connected to the mainland by two small bridges. Ortygia is becoming increasingly popular with tourists, and is starting to lose its old-fashioned charm in favor of modern boutiques.Siracusa's old nucleus of Ortygia, a compact area, is a pleasure to amble around without getting unduly tired. In contrast, mainland Siracusa is a grid of wider avenues. At the northern end of Corso Gelone, above Viale Paolo Orsi, the orderly grid gives way to the ancient quarter of Neapolis, where the sprawling Parco Archeologico is accessible from Viale Teracati (an extension of Corso Gelone). East of Viale Teracati, about a 10-minute walk from the Parco Archeologico, the district of Tyche holds the archaeological museum and the church and catacombs of San Giovanni, both off Viale Teocrito (drive or take a taxi or city bus from Ortygia). Coming from the train station, it's a 15-minute trudge to Ortygia along Via Francesco Crispi and Corso Umberto. If you're not up for that, take one of the free electric buses leaving every 10 minutes from the bus station around the corner.

Malta's capital, the minicity of Valletta, has ornate palaces and museums protected by massive fortifications of honey-color limestone. Houses along the narrow streets have overhanging wooden balconies for people-watching from indoors. Generations ago they gave housebound women a window on the world of the street. The main entrance to town is through the City Gate (where all bus routes end), which leads onto Triq Repubblika (Republic Street), the spine of the grid-pattern city and the main shopping street. Triq Mercante (Merchant Street) parallels Repubblika to the east and is also good for strolling. From these two streets, cross streets descend toward the water; some are stepped. Valletta's compactness makes it ideal to explore on foot. City Gate and the upper part of Valletta are experiencing vast redevelopment that includes a new Parliament Building and open-air performance venue. The complex, completed mid-2013, has numerous pedestrian detours in place along with building noise and dust. Before setting out along Republic Street, stop at the tourist information office on Merchant Street for maps and brochures.

Although the fishing boats still go out in good weather, Mykonos largely makes its living from tourism these days. The summer crowds have turned one of the poorest islands in Greece into one of the richest. Old Mykonians complain that their young, who have inherited stores where their grandfathers once sold eggs or wine, get so much rent that they have lost ambition, and in summer sit around pool bars at night with their friends, and hang out in Athens in winter when island life is less scintillating. Put firmly on the map by Jackie O in the 1960s, Mykonos town—called Hora by the locals—remains the Saint-Tropez of the Greek islands. The scenery is memorable, with its whitewashed streets, Little Venice, the Kato Myli ridge of windmills, and Kastro, the town's medieval quarter. Its cubical two- or three-story houses and churches, with their red or blue doors and domes and wooden balconies, have been long celebrated as some of the best examples of classic Cycladic architecture. Luckily, the Greek Archaeological Service decided to preserve the town, even when the Mykonians would have preferred to rebuild, and so the Old Town has been impressively preserved. Pink oleander, scarlet hibiscus, and trailing green pepper trees form a contrast amid the dazzling whiteness, whose frequent renewal with whitewash is required by law. Any visitor who has the pleasure of getting lost in its narrow streets (made all the narrower by the many outdoor stone staircases, which maximize housing space in the crowded village) will appreciate how its confusing layout was designed to foil pirates—if it was designed at all. After Mykonos fell under Turkish rule in 1537, the Ottomans allowed the islanders to arm their vessels against pirates, which had a contradictory effect: many of them found that raiding other islands was more profitable than tilling arid land. At the height of Aegean piracy, Mykonos was the principal headquarters of the corsair fleets—the place where pirates met their fellows, found willing women, and filled out their crews. Eventually the illicit activity evolved into a legitimate and thriving trade network. Morning on Mykonos town's main quay is busy with deliveries, visitors for the Delos boats, lazy breakfasters, and street cleaners dealing with the previous night's mess. In late morning the cruise-boat people arrive, and the shops are all open. In early afternoon, shaded outdoor tavernas are full of diners eating salads (Mykonos's produce is mostly imported); music is absent or kept low. In mid- and late afternoon, the town feels sleepy, since so many people are at the beach, on excursions, or sleeping in their air-conditioned rooms; even some tourist shops close for siesta. By sunset, people have come back from the beach, having taken their showers and rested. At night, the atmosphere in Mykonos ramps up. The cruise-boat people are mostly gone, coughing three-wheelers make no deliveries in the narrow streets, and everyone is dressed sexy for summer and starting to shimmy with the scene. Many shops stay open past midnight, the restaurants fill up, and the bars and discos make ice cubes as fast as they can. Ready to dive in? Begin your tour of Mykonos town (Hora) by starting out at its heart: Mando Mavrogenous Square.

For better or worse, it can be difficult to reach Patmos—for many travelers, this lack of access is definitely for the better, since the island retains the air of an unspoiled retreat. Rocky and barren, the small, 34-square-km (21-square-mi) island lies beyond the islands of Kalymnos and Leros, northwest of Kos. Here on a hillside is the Monastery of the Apocalypse, which enshrines the cave where St. John received the Revelation in AD 95. Scattered evidence of Mycenaean presence remains on Patmos, and walls of the classical period indicate the existence of a town near Skala. Most of the island's approximately 2,800 people live in three villages: Skala, medieval Chora, and the small rural settlement of Kambos. The island is popular among the faithful making pilgrimages to the monastery as well as with vacationing Athenians and a newly growing community of international trendsetters—designers, artists, poets, and “taste gurus” (to quote Vogue’s July 2011 write-up of the island)—who have bought homes in Chora. These stylemeisters followed in the footsteps of Alexandrian John Stefanidis and the English artist Teddy Millington-Drake who, in the early ’60s, set about creating what eventually became hailed as one of the most gorgeous island homes in the world. The word soon spread thanks to their many guests (who included Jacqueline Kennedy Onassis) but, happily, administrators have carefully contained development, and as a result, Patmos retains its charm and natural beauty—even in the busy month of August.

Undoubtedly the most extraordinary island in the Aegean, crescent-shape Santorini remains a mandatory stop on the Cycladic tourist route—even if it's necessary to enjoy the sensational sunsets from Ia, the fascinating excavations, and the dazzling white towns with a million other travelers. Called Kállisti (the "Loveliest") when first settled, the island has now reverted to its subsequent name of Thira, after the 9th-century-BC Dorian colonizer Thiras. The place is better known, however, these days as Santorini, a name derived from its patroness, St. Irene of Thessaloniki, the Byzantine empress who restored icons to Orthodoxy and died in 802. You can fly conveniently to Santorini, but to enjoy a true Santorini rite of passage, opt instead for the boat trip here, which provides a spectacular introduction. After the boat sails between Sikinos and Ios, your deck-side perch approaches two close islands with a passage between them. The bigger one on the left is Santorini, and the smaller on the right is Thirassia. Passing between them, you see the village of Ia adorning Santorini's northernmost cliff like a white geometric beehive. You are in the caldera (volcanic crater), one of the world's truly breathtaking sights: a demilune of cliffs rising 1,100 feet, with the white clusters of the towns of Fira and Ia perched along the top. The bay, once the high center of the island, is 1,300 feet in some places, so deep that when boats dock in Santorini's shabby little port of Athinios, they do not drop anchor. The encircling cliffs are the ancient rim of a still-active volcano, and you are sailing east across its flooded caldera. On your right are the Burnt isles, the White isle, and other volcanic remnants, all lined up as if some outsize display in a geology museum. Hephaestus's subterranean fires smolder still—the volcano erupted in 198 BC, about 735, and there was an earthquake in 1956. Indeed, Santorini and its four neighboring islets are the fragmentary remains of a larger landmass that exploded about 1600 BC: the volcano's core blew sky high, and the sea rushed into the abyss to create the great bay, which measures 10 km by 7 km (6 mi by 4½ mi) and is 1,292 feet deep. The other pieces of the rim, which broke off in later eruptions, are Thirassia, where a few hundred people live, and deserted little Aspronissi ("White isle"). In the center of the bay, black and uninhabited, two cones, the Burnt Isles of Palea Kameni and Nea Kameni, appeared between 1573 and 1925. There has been too much speculation about the identification of Santorini with the mythical Atlantis, mentioned in Egyptian papyri and by Plato (who says it's in the Atlantic), but myths are hard to pin down. This is not true of old arguments about whether tidal waves from Santorini's cataclysmic explosion destroyed Minoan civilization on Crete, 113 km (70 mi) away. The latest carbon-dating evidence, which points to a few years before 1600 BC for the eruption, clearly indicates that the Minoans outlasted the eruption by a couple of hundred years, but most probably in a weakened state. In fact, the island still endures hardships: since antiquity, Santorini has depended on rain collected in cisterns for drinking and irrigating—the well water is often brackish—and the serious shortage is alleviated by the importation of water. However, the volcanic soil also yields riches: small, intense tomatoes with tough skins used for tomato paste (good restaurants here serve them); the famous Santorini fava beans, which have a light, fresh taste; barley; wheat; and white-skin eggplants.

It's no wonder that all roads lead to the fascinating and maddening metropolis of Athens. Lift your eyes 200 feet above the city to the Parthenon, its honey-color marble columns rising from a massive limestone base, and you behold architectural perfection that has not been surpassed in 2,500 years. But, today, this shrine of classical form dominates a 21st-century boomtown. To experience Athens—Athína in Greek—fully is to understand the essence of Greece: ancient monuments surviving in a sea of cement, startling beauty amid the squalor, tradition juxtaposed with modernity. Locals depend on humor and flexibility to deal with the chaos; you should do the same. The rewards are immense. Although Athens covers a huge area, the major landmarks of the ancient Greek, Roman, and Byzantine periods are close to the modern city center. You can easily walk from the Acropolis to many other key sites, taking time to browse in shops and relax in cafés and tavernas along the way. From many quarters of the city you can glimpse "the glory that was Greece" in the form of the Acropolis looming above the horizon, but only by actually climbing that rocky precipice can you feel the impact of the ancient settlement. The Acropolis and Filopappou, two craggy hills sitting side by side; the ancient Agora (marketplace); and Kerameikos, the first cemetery, form the core of ancient and Roman Athens. Along the Unification of Archaeological Sites promenade, you can follow stone-paved, tree-lined walkways from site to site, undisturbed by traffic. Cars have also been banned or reduced in other streets in the historical center. In the National Archaeological Museum, vast numbers of artifacts illustrate the many millennia of Greek civilization; smaller museums such as the Goulandris Museum of Cycladic Art Museum and the Byzantine and Christian Museum illuminate the history of particular regions or periods. Athens may seem like one huge city, but it is really a conglomeration of neighborhoods with distinctive characters. The Eastern influences that prevailed during the 400-year rule of the Ottoman Empire are still evident in Monastiraki, the bazaar area near the foot of the Acropolis. On the northern slope of the Acropolis, stroll through Plaka (if possible by moonlight), an area of tranquil streets lined with renovated mansions, to get the flavor of the 19th-century's gracious lifestyle. The narrow lanes of Anafiotika, a section of Plaka, thread past tiny churches and small, color-washed houses with wooden upper stories, recalling a Cycladic island village. In this maze of winding streets, vestiges of the older city are everywhere: crumbling stairways lined with festive tavernas; dank cellars filled with wine vats; occasionally a court or diminutive garden, enclosed within high walls and filled with magnolia trees and the flaming trumpet-shaped flowers of hibiscus bushes. Formerly run-down old quarters, such as Thission, Gazi and Psirri, popular nightlife areas filled with bars and mezedopoleia (similar to tapas bars), are now in the process of gentrification, although they still retain much of their original charm, as does the colorful produce and meat market on Athinas. The area around Syntagma Square, the tourist hub, and Omonia Square, the commercial heart of the city about 1 km (½ mi) northwest, is distinctly European, having been designed by the court architects of King Otho, a Bavarian, in the 19th century. The chic shops and bistros of ritzy Kolonaki nestle at the foot of Mt. Lycabettus, Athens's highest hill (909 feet). Each of Athens's outlying suburbs has a distinctive character: in the north is wealthy, tree-lined Kifissia, once a summer resort for aristocratic Athenians, and in the south and southeast lie Glyfada, Voula, and Vouliagmeni, with their sandy beaches, seaside bars, and lively summer nightlife. Just beyond the city's southern fringes is Piraeus, a bustling port city of waterside fish tavernas and Saronic Gulf views.
