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.

Known in Sardinia as Casteddu, the island's capital has steep streets and impressive Italianate architecture, from modern to medieval. This city of nearly 160,000 people is characterized by a busy commercial center and waterfront with broad avenues and arched arcades, as well as by the typically narrow streets of the old hilltop citadel (called, simply, “Castello”). The Museo Archeologico makes a good starting point to a visit. The imposing Bastione di Saint Remy and Mercato di San Benedetto (one of the best fish markets in Italy) are both musts.

Katakolon could not seem less of a cruise port if it tried. A tiny enclave clinging to the western Peloponnese coast, it's a sleepy place except when ships dock. But it's a popular cruise destination because of its proximity to Olympia. Ancient Olympia was one of the most important cities in classical Greece. The Sanctuary of Zeus was the city's raison d'être, and attracted pilgrims from around the eastern Mediterranean, and later the city played host to Olympic Games, the original athletic games that were the inspiration for today's modern sporting pan-planetary meet. At the foot of the tree-covered Kronion hill, in a valley near two rivers, Katakolon is today one of the most popular ancient sites in Greece. If you don't want to make the trip to Olympia, then Katakolon is an ideal place for a leisurely Greek lunch while you watch the fishermen mend their nets, but there's just not much else to do there.

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

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.

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.

Believed to be the oldest town on the Iberian Peninsula, the Andalusian port of Cádiz enjoys a stunning location at the edge of a six-mile promontory. The town itself, with 3,000 years of history, is characterised by pretty white houses with balconies often adorned with colourful flowers. As you wander around be sure to take a stroll through the sizeable Plaza de Espãna, with its large monument dedicated to the first Spanish constitution, which was signed here in 1812. Cádiz has two pleasant seafront promenades which boast fine views of the Atlantic Ocean, and has a lovely park, the Parque Genoves, located close to the sea with an open-air theatre and attractive palm garden. Also notable is the neo-Classical cathedral, capped by a golden dome.

Lying near the head of Southampton Water, a peninsula between the estuaries of the Rivers Test and Itchen, Southampton is Britain’s largest cruise port. It has been one of England’s major ports since the Middle Ages, when it exported wool and hides from the hinterland and imported wine from Bordeaux. The city suffered heavy damage during World War Two and as a result the centre has been extensively rebuilt, but there are still some interesting medieval buildings including the Bargate, one of the finest city gatehouses in England.
