Just 22 nautical miles down river from the Tower Bridge in London, Tilbury is a popular turnaround port for cruises visiting Baltic and Northern European destinations.

The autonomous city of Ceuta is a tiny Spanish city-enclave on the Moroccan side of the Straits of Gibraltar, separated from the Spanish mainland by just 12 miles. The city's strategic location has ensured it has endured a turbulent history, often being used as a trade and military outpost. Originally an old Carthaginian colony, it has since been held by the Romans, Vandals, Byzantines, and Arabs, and has been known as 'Abyla', 'Septem' and 'Cibta'. It was finally taken over by Spain in 1580 and has remained Spanish since then, with the name 'Ceuta'. Covering an area of just ten square miles, the enclave is dominated by the hill of Monte Hacho, sometimes believed to be the legendary Pillars of Hercules. With a fascinating mix of both Spanish and African influences and surrounded by massive 14th-century city walls, Ceuta has a charm and grandeur all of its own. As an autonomous region of Spain, Ceuta is part of the territory of the EU, but is considered a special low-tax zone. Leather goods, ceramics and embroidery are common purchases from the city.

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.

Valencia, Spain's third-largest municipality, is a proud city with a thriving nightlife and restaurant scene, quality museums, and spectacular contemporary architecture, juxtaposed with a thoroughly charming historic quarter, making it a popular destination year in year out. During the Civil War, it was the last seat of the Republican Loyalist government (1935–36), holding out against Franco’s National forces until the country fell to 40 years of dictatorship. Today it represents the essence of contemporary Spain—daring design and architecture along with experimental cuisine—but remains deeply conservative and proud of its traditions. Though it faces the Mediterranean, Valencia's history and geography have been defined most significantly by the River Turia and the fertile huerta that surrounds it.The city has been fiercely contested ever since it was founded by the Greeks. El Cid captured Valencia from the Moors in 1094 and won his strangest victory here in 1099: he died in the battle, but his corpse was strapped into his saddle and so frightened the besieging Moors that it caused their complete defeat. In 1102 his widow, Jimena, was forced to return the city to Moorish rule; Jaume I finally drove them out in 1238. Modern Valencia was best known for its frequent disastrous floods until the River Turia was diverted to the south in the late 1950s. Since then the city has been on a steady course of urban beautification. The lovely bridges that once spanned the Turia look equally graceful spanning a wandering municipal park, and the spectacularly futuristic Ciutat de les Arts i les Ciències (City of Arts and Sciences), most of it designed by Valencia-born architect Santiago Calatrava, has at last created an exciting architectural link between this river town and the Mediterranean. If you're in Valencia, an excursion to Albufera Nature Park is a worthwhile day trip.

Ground literally to ashes in World War II and wracked by a massive earthquake a decade later, the capital of Kefalonia once more shows pride in its native spirit and natural beauty. The vast harbor on Argostoli’s east side makes an especially attractive port for cruise ships full of visitors who never seem to tire of strolling the cobbled seaside promenade, sipping ouzos in cafés, and stocking up on the succulent Mediterranean fruits in the outdoor markets.

Corfu town today is a vivid tapestry of cultures—a sophisticated weave, where charm, history, and natural beauty blend. Located about midway along the island's east coast, this spectacularly lively capital is the cultural heart of Corfu and has a remarkable historic center that UNESCO designated as a World Heritage Site in 2007. All ships and planes dock or land near Corfu town, which occupies a small peninsula jutting into the Ionian Sea.Whether arriving by ferry from mainland Greece or Italy, from another island, or directly by plane, catch your breath by first relaxing with a coffee or a gelato in Corfu town's shaded Liston Arcade, then stroll the narrow lanes of its pedestrians-only quarter. For an overview of the immediate area, and a quick tour of Mon Repos palace, hop on the little tourist train that runs from May to September. Corfu town has a different feel at night, so book a table at one of its famed tavernas to savor the island's unique cuisine.The best way to get around Corfu town is on foot. The town is small enough so that you can easily walk to every sight. There are local buses, but they do not thread their way into the streets (many now car-free) of the historic center. If you are arriving by ferry or plane, it's best to take a taxi to your hotel. Expect to pay about €10 from the airport or ferry terminal to a hotel in Corfu town. If there are no taxis waiting, you can call for one.

Nothing can prepare you for your first sight of Dubrovnik. Lying 216 km (135 miles) southeast of Split and commanding a jaw-dropping coastal location, it is one of the world's most beautiful fortified cities. Its massive stone ramparts and fortress towers curve around a tiny harbor, enclosing graduated ridges of sun-bleached orange-tiled roofs, copper domes, and elegant bell towers. Your imagination will run wild picturing what it looked like seven centuries ago when the walls were built, without any suburbs or highways around it, just this magnificent stone city rising out of the sea.In the 7th century AD, residents of the Roman city Epidaurum (now Cavtat) fled the Avars and Slavs of the north and founded a new settlement on a small rocky island, which they named Laus, and later Ragusa. On the mainland hillside opposite the island, the Slav settlement called Dubrovnik grew up. In the 12th century the narrow channel separating the two settlements was filled in (now the main street through the Old Town, called Stradun), and Ragusa and Dubrovnik became one. The city was surrounded by defensive walls during the 13th century, and these were reinforced with towers and bastions in the late 15th century.From 1358 to 1808 the city thrived as a powerful and remarkably sophisticated independent republic, reaching its golden age during the 16th century. In 1667 many of its splendid Gothic and Renaissance buildings were destroyed by an earthquake. The defensive walls survived the disaster, and the city was rebuilt in baroque style.Dubrovnik lost its independence to Napoléon in 1808, and in 1815 passed to Austria-Hungary. During the 20th century, as part of Yugoslavia, the city became a popular tourist destination, and in 1979 it was listed as a UNESCO World Heritage Site. During the war for independence, it came under heavy siege. Thanks to careful restoration, few traces of damage remain; however, there are maps inside the Pile and Ploče Gates illustrating the points around the city where damage was done. It’s only when you experience Dubrovnik yourself that you can understand what a treasure the world nearly lost

Backed by imposing mountains, tiny Kotor lies hidden from the open sea, tucked into the deepest channel of the Bokor Kotorska (Kotor Bay), which is Europe's most southerly fjord. To many, this town is more charming than its sister UNESCO World Heritage Site, Dubrovnik, retaining more authenticity, but with fewer tourists and spared the war damage and subsequent rebuilding which has given Dubrovnik something of a Disney feel.Kotor's medieval Stari Grad (Old Town) is enclosed within well-preserved defensive walls built between the 9th and 18th centuries and is presided over by a proud hilltop fortress. Within the walls, a labyrinth of winding cobbled streets leads through a series of splendid paved piazzas, rimmed by centuries-old stone buildings. The squares are now haunted by strains from buskers but although many now house trendy cafés and chic boutiques, directions are still given medieval-style by reference to the town’s landmark churches.In the Middle Ages, as Serbia's chief port, Kotor was an important economic and cultural center with its own highly regarded schools of stonemasonry and iconography. From 1391 to 1420 it was an independent city-republic and later, it spent periods under Venetian, Austrian, and French rule, though it was undoubtedly the Venetians who left the strongest impression on the city's architecture. Since the breakup of Yugoslavia, some 70% of the stone buildings in the romantic Old Town have been snapped up by foreigners, mostly Brits and Russians. Porto Montenegro, a new marina designed to accommodate some of the world’s largest super yachts, opened in nearby Tivat in 2011, and along the bay are other charming seaside villages, all with better views of the bay than the vista from Kotor itself where the waterside is congested with cruise ships and yachts. Try sleepy Muo or the settlement of Prčanj in one direction around the bay, or Perast and the Roman mosaics of Risan in the other direction.

Split's ancient core is so spectacular and unusual that a visit is more than worth your time. The heart of the city lies within the walls of Roman emperor Diocletian's retirement palace, which was built in the 3rd century AD. Diocletian, born in the nearby Roman settlement of Salona in AD 245, achieved a brilliant career as a soldier and became emperor at the age of 40. In 295 he ordered this vast palace to be built in his native Dalmatia, and when it was completed he stepped down from the throne and retired to his beloved homeland. Upon his death, he was laid to rest in an octagonal mausoleum, around which Split's magnificent cathedral was built.In 615, when Salona was sacked by barbarian tribes, those fortunate enough to escape found refuge within the stout palace walls and divided up the vast imperial apartments into more modest living quarters. Thus, the palace developed into an urban center, and by the 11th century the settlement had expanded beyond the ancient walls.Under the rule of Venice (1420–1797), Split—as a gateway to the Balkan interior—became one of the Adriatic's main trading ports, and the city's splendid Renaissance palaces bear witness to the affluence of those times. When the Habsburgs took control during the 19th century, an overland connection to Central Europe was established by the construction of the Split–Zagreb–Vienna railway line.After World War II, the Tito years saw a period of rapid urban expansion: industrialization accelerated and the suburbs extended to accommodate high-rise apartment blocks. Today the historic center of Split is included on UNESCO's list of World Heritage Sites.

Dalmatia's capital for more than 1,000 years, Zadar is all too often passed over by travelers on their way to Split or Dubrovnik. What they miss out on is a city of more than 73,000 that is remarkably lovely and lively despite—and, in some measure, because of—its tumultuous history. The Old Town, separated from the rest of the city on a peninsula some 4 km (2½ miles) long and just 1,640 feet wide, is bustling and beautiful: the marble pedestrian streets are replete with Roman ruins, medieval churches, palaces, museums, archives, and libraries. Parts of the new town are comparatively dreary, a testament to what a world war followed by decades of communism, not to mention a civil war, can do to the architecture of a city that is 3,000 years old. A settlement had already existed on the site of the present-day city for some 2,000 years when Rome finally conquered Zadar in the 1st century BC; the foundations of the forum can be seen today. Before the Romans came the Liburnians had made it a key center for trade with the Greeks and Romans for 800 years. In the 3rd century BC the Romans began to seriously pester the Liburnians, but required two centuries to bring the area under their control. During the Byzantine era, Zadar became the capital of Dalmatia, and this period saw the construction of its most famous church, the 9th-century St. Donat's Basilica. It remained the region's foremost city through the ensuing centuries. The city then experienced successive onslaughts and occupations—both long and short—by the Osogoths, the Croatian-Hungarian kings, the Venetians, the Turks, the Habsburgs, the French, the Habsburgs again, and finally the Italians before becoming part of Yugoslavia and, in 1991, the independent republic of Croatia. Zadar was for centuries an Italian-speaking city, and Italian is still spoken widely, especially by older people. Indeed, it was ceded to Italy in 1921 under the Treaty of Rapallo (and reverted to its Italian name of Zara). Its occupation by the Germans from 1943 led to intense bombing by the Allies during World War II, which left most of the city in ruins. Zadar became part of Tito's Yugoslavia in 1947, prompting many Italian residents to leave. Zadar's most recent ravages occurred during a three-month siege by Serb forces and months more of bombardment during the Croatian-Serbian war between 1991 and 1995. But you'd be hard-pressed to find outward signs of this today in what is a city to behold. There are helpful interpretive signs in English all around the Old Town, so you certainly won't feel lost when trying to make sense of the wide variety of architectural sites you might otherwise pass by with only a cursory look.

Up until the end of World War I, Trieste was the only port of the vast Austro-Hungarian Empire and therefore a major industrial and financial center. In the early years of the 20th century, Trieste and its surroundings also became famous by their association with some of the most important names of Italian literature, such as Italo Svevo, and English and German letters. James Joyce drew inspiration from the city's multiethnic population, and Rainer Maria Rilke was inspired by the seacoast west of the city. Although it has lost its importance as a port and a center of finance, it has never fully lost its roll as an intellectual center. The streets hold a mix of monumental, neoclassical, and art-nouveau architecture built by the Austrians during Trieste's days of glory, granting an air of melancholy stateliness to a city that lives as much in the past as the present.

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.

If you look north of the cathedral (La Seu, or the seat of the bishopric, to Mallorcans) on a map of the city of Palma, you can see around the Plaça Santa Eulàlia a jumble of tiny streets that made up the earliest settlement. Farther out, a ring of wide boulevards traces the fortifications built by the Moors to defend the larger city that emerged by the 12th century. The zigzags mark the bastions that jutted out at regular intervals. By the end of the 19th century, most of the walls had been demolished; the only place where you can still see the massive defenses is at Ses Voltes, along the seafront west of the cathedral.A torrent (streambed) used to run through the middle of the old city, dry for most of the year but often a raging flood in the rainy season. In the 17th century it was diverted to the east, along the moat that ran outside the city walls. Two of Palma's main arteries, La Rambla and the Passeig d'es Born, now follow the stream's natural course. The traditional evening paseo (promenade) takes place on the Born.If you come to Palma by car, park in the garage beneath the Parc de la Mar (the ramp is just off the highway from the airport, as you reach the cathedral) and stroll along the park. Beside it run the huge bastions guarding the Almudaina Palace; the cathedral, golden and massive, rises beyond. Where you exit the garage, there's a ceramic mural by the late Catalan artist and Mallorca resident Joan Miró, facing the cathedral across the pool that runs the length of the park.If you begin early enough, a walk along the ramparts at Ses Voltes from the mirador beside the cathedral is spectacular. The first rays of the sun turn the upper pinnacles of La Seu bright gold and then begin to work their way down the sandstone walls. From the Parc de la Mar, follow Avinguda Antoni Maura past the steps to the palace. Just below the Plaça de la Reina, where the Passeig d'es Born begins, turn left on Carrer de la Boteria into the Plaça de la Llotja (if the Llotja itself is open, don't miss a chance to visit—it's the Mediterranean's finest Gothic-style civic building). From there stroll through the Plaça Drassana to the Museu d'Es Baluard, at the end of Carrer Sant Pere. Retrace your steps to Avinguda Antoni Maura. Walk up the Passeig d'es Born to Plaça Joan Carles I, then right on Avenida de La Unió.

Set on seven hills on the banks of the River Tagus, Lisbon has been the capital of Portugal since the 13th century. It is a city famous for its majestic architecture, old wooden trams, Moorish features and more than twenty centuries of history. Following disastrous earthquakes in the 18th century, Lisbon was rebuilt by the Marques de Pombal who created an elegant city with wide boulevards and a great riverfront and square, Praça do Comércio. Today there are distinct modern and ancient sections, combining great shopping with culture and sightseeing in the Old Town, built on the city's terraced hillsides. The distance between the ship and your tour vehicle may vary. This distance is not included in the excursion grades.

El Ferrol has been inextricably linked to the sea for more than two millennia, being a major shipbuilding centre for most of its history. From its beginnings as a tiny fishing port in the 1st century BC, it endured conquests by Vandals, Suebis, Arabs and Christians. With the arrival of the Bourbons in the 18th century, Ferrol became a leading maritime centre, largely due to its large natural harbour on the Ferrol Inlet, an arm of the Atlantic. Now a large commercial port, Ferrol is also the gateway to the northern Spanish province of Galicia, a region noted for its green mountains, deep gorges and fast-flowing rivers. It is also well placed for visiting the medieval holy city of Santiago de Compostela. Interestingly, Ferrol's city centre is modelled on Lisbon in Portugal, a country with which it has strong historical and linguistic ties. The layout comprises of a rectangle lined with six parallel streets, with two squares on each side. These squares have the city's best shops, restaurants and bars.

Just 22 nautical miles down river from the Tower Bridge in London, Tilbury is a popular turnaround port for cruises visiting Baltic and Northern European destinations.
