20-Day World Cruise Segment-Rome (Civitavecchia) to London (Dover)

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.

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.

A Mediterranean city and naval station located in the Region of Murcia, southeastern Spain, Cartagena’s sheltered bay has attracted sailors for centuries. The Carthaginians founded the city in 223BC and named it Cartago Nova; it later became a prosperous Roman colony, and a Byzantine trading centre. The city has been the main Spanish Mediterranean naval base since the reign of King Philip II, and is still surrounded by walls built during this period. Cartagena’s importance grew with the arrival of the Spanish Bourbons in the 18th century, when the Navidad Fortress was constructed to protect the harbour. In recent years, traces of the city’s fascinating past have been brought to light: a well-preserved Roman Theatre was discovered in 1988, and this has now been restored and opened to the public. During your free time, you may like to take a mini-cruise around Cartagena's historic harbour: these operate several times a day, take approximately 40 minutes and do not need to be booked in advance. Full details will be available at the port.

Tangier can trace its origins back to the Phoenicians and ancient Greeks. It was named after Tinge, the mother of Hercules’ son, and its beginnings are embedded in mythology. It was subsequently a Roman province, and after Vandal and Byzantine influences, was occupied by the Arabs with Spain, Portugal, France and England also playing a part in the city’s history. With such a diverse past it is perhaps not surprising that Tangier is such an individual city. Overlooking the Straits of Gibraltar, the city lies on a bay between two promontories. With its old Kasbah, panoramic views, elegant buildings, squares and places of interest, there is much to discover in both the new and old parts of the city.

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.

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.

Time in Bilbao (Bilbo, in Euskera) may be recorded as BG or AG (Before Guggenheim or After Guggenheim). Never has a single monument of art and architecture so radically changed a city. Frank Gehry's stunning museum, Norman Foster's sleek subway system, the Santiago Calatrava glass footbridge and airport, the leafy César Pelli Abandoibarra park and commercial complex next to the Guggenheim, and the Philippe Starck AlhóndigaBilbao cultural center have contributed to an unprecedented cultural revolution in what was once the industry capital of the Basque Country.Greater Bilbao contains almost 1 million inhabitants, nearly half the total population of the Basque Country. Founded in 1300 by Vizcayan noble Diego López de Haro, Bilbao became an industrial center in the mid-19th century, largely because of the abundance of minerals in the surrounding hills. An affluent industrial class grew up here, as did the working class in suburbs that line the Margen Izquierda (Left Bank) of the Nervión estuary.Bilbao's new attractions get more press, but the city's old treasures still quietly line the banks of the rust-color Nervión River. The Casco Viejo (Old Quarter)—also known as Siete Calles (Seven Streets)—is a charming jumble of shops, bars, and restaurants on the river's Right Bank, near the Puente del Arenal bridge. This elegant proto-Bilbao nucleus was carefully restored after devastating floods in 1983. Throughout the Casco Viejo are ancient mansions emblazoned with family coats of arms, wooden doors, and fine ironwork balconies. The most interesting square is the 64-arch Plaza Nueva, where an outdoor market is pitched every Sunday morning.Walking the banks of the Nervión is a satisfying jaunt. After all, this was how—while out on a morning jog—Guggenheim director Thomas Krens first discovered the perfect spot for his project, nearly opposite the right bank's Deusto University. From the Palacio de Euskalduna upstream to the colossal Mercado de la Ribera, parks and green zones line the river. César Pelli's Abandoibarra project fills in the half mile between the Guggenheim and the Euskalduna bridge with a series of parks, the Deusto University library, the Meliá Bilbao Hotel, and a major shopping center.On the left bank, the wide, late-19th-century boulevards of the Ensanche neighborhood, such as Gran Vía (the main shopping artery) and Alameda de Mazarredo, are the city's more formal face. Bilbao's cultural institutions include, along with the Guggenheim, a major museum of fine arts (the Museo de Bellas Artes) and an opera society (Asociación Bilbaína de Amigos de la Ópera, or ABAO) with 7,000 members from Spain and southern France. In addition, epicureans have long ranked Bilbao's culinary offerings among the best in Spain. Don't miss a chance to ride the trolley line, the Euskotram, for a trip along the river from Atxuri Station to Basurto's San Mamés soccer stadium, reverently dubbed "la Catedral del Fútbol" (the Cathedral of Football).

Situated on the Garonne River, 70 miles (113 km) inland from the Atlantic, Bordeaux's origin can be traced back to the 3rd century when it was Aquitaine's Roman capital called Burdigala. From 1154 to 1453, the town prospered under the rule of the English, whose fondness for the region's red wines gave impetus to the local wine industry. At various times, Bordeaux even served as the nation's capital: in 1870, at the beginning of World War I, and for two weeks in 1940 before the Vichy government was proclaimed. Bordeaux's neo-classical architecture, wide avenues and well-tended public squares and parks lend the city a certain grandeur. Excellent museums, an imposing cathedral and a much-praised theatre add to the city's attractions. The principal highlights, clustered around the town centre, can easily be explored on foot.

Cork City's nearby harbor district has seen plenty of history. Cork Harbour's draws include Fota Island—with an arboretum, a wildlife park, and the Fota House ancestral estate—and the fishing port of Cobh.

Trendy stores, a booming cultural life, fascinating architecture, and stylish restaurants reinforce Glasgow's claim to being Scotland's most exciting city. After decades of decline, it has experienced an urban renaissance uniquely its own. The city’s grand architecture reflects a prosperous past built on trade and shipbuilding. Today buildings by Charles Rennie Mackintosh hold pride of place along with the Zaha Hadid–designed Riverside Museum.Glasgow (the "dear green place," as it was known) was founded some 1,500 years ago. Legend has it that the king of Strathclyde, irate about his wife's infidelity, had a ring he had given her thrown into the river Clyde. (Apparently she had passed it on to an admirer.) When the king demanded to know where the ring had gone, the distraught queen asked the advice of her confessor, St. Mungo. He suggested fishing for it—and the first salmon to emerge had the ring in its mouth. The moment is commemorated on the city's coat of arms.The medieval city expanded when it was given a royal license to trade; the current High Street was the main thoroughfare at the time. The vast profits from American cotton and tobacco built the grand mansions of the Merchant City in the 18th century. In the 19th century the river Clyde became the center of a vibrant shipbuilding industry, fed by the city’s iron and steel works. The city grew again, but its internal divisions grew at the same time. The West End harbored the elegant homes of the newly rich shipyard owners. Down by the river, areas like the infamous Gorbals, with its crowded slums, sheltered the laborers who built the ships. They came from the Highlands, expelled to make way for sheep, or from Ireland, where the potato famines drove thousands from their homes.During the 19th century the population grew from 80,000 to more than a million. And the new prosperity gave Glasgow its grand neoclassical buildings, such as those built by Alexander "Greek" Thomson, as well as the adventurous visionary buildings designed by Charles Rennie Mackintosh and others who produced Glasgow’s Arts and Crafts movement. The City Chambers, built in 1888, are a proud statement in marble and gold sandstone, a clear symbol of the wealthy and powerful Victorian industrialists' hopes for the future.The decline of shipbuilding and the closure of the factories led to much speculation as to what direction the city would take now. The curious thing is that, at least in part, the past gave the city a new lease of life. It was as if people looked at their city and saw Glasgow’s beauty for the first time: its extraordinarily rich architectural heritage, its leafy parks, its artistic heritage, and its complex social history. Today Glasgow is a vibrant cultural center and a commercial hub, as well as a launching pad from which to explore the rest of Scotland, which, as it turns out, is not so far away. In fact, it takes only 40 minutes to reach Loch Lomond, where the other Scotland begins.

From world-class attractions and sports to legendary music, Liverpool offers old-world charm with modern sophistication, underpinned by a rich cultural history.

Known as the gateway of England, Dover welcomes millions of visitors from all over the globe each year in its role as the ferry capital of the world and the second busiest cruise port in the UK. The White Cliffs Country has a rich heritage. Within the walls of the town’s iconic castle, over 2,000 years of history waits to be explored, whilst the town’s museum is home to the Dover Bronze Age Boat, the world’s oldest known seagoing vessel. The town’s cliffs that are a welcome sight for today's cross-channel travellers also served as the control centre for the Dunkirk evacuation in 1940.
