Ever since the Romans constructed a fort here and began using it as a trading post, Oporto has been a prosperous commercial centre. In the 15th and 16th centuries the city benefited from the wealth generated by Portugal’s maritime discoveries, and later, the establishment of a lucrative wine trade with Britain compensated for the loss of the spice trade. Today, Portugal’s second-largest city is a thriving, cosmopolitan place and is famous for its production of the fortified, sweet 'port' wine. Its historic centre is a UNESCO World Heritage Site and the city was also awarded the status of European Capital of Culture in 2001. A large sandbar prevents ships from sailing into Oporto itself, so for over a century they have used nearby Leixões instead, a man-made seaport constructed nine miles from the city. Leixões is one of Portugal's major sea ports and is also home to one of the country's oldest football clubs, winners of the Taça de Portugal cup in 1961.

Tagged on to the end of Iberia, the intriguing British outpost of Gibraltar is dominated by a sandy peninsula and the stunning 1,400-feet-high limestone Rock. Although small, Gibraltar has always been seen as having great strategic importance on account of its advantageous position where the Atlantic meets the Mediterranean, just 12 miles from the coast of Africa. Ever popular with British holidaymakers, Gibraltar is very much a home from home, boasting excellent duty-free shopping in many familiar British high street shops. Please note: Gibraltar’s small size and narrow winding roads mean that excursions are operated by 22-seater mini-buses, accompanied by a driver/guide. Local health and safety regulations prohibit the carriage of walking aids and collapsible wheelchairs on these vehicles. If you do wish to bring a mobility aid, we can arrange the Rock Tour by taxi, which has extra space. If this suits your requirements, please advise the Tours and Travel office when you join the ship, as numbers are limited.

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.

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.

Hedonistic and historic, Eivissa (Ibiza, in Castilian) is a city jam-packed with cafés, nightspots, and trendy shops; looming over it are the massive stone walls of Dalt Vila —the medieval city declared a UNESCO World Heritage site in 1999—and its Gothic cathedral. Squeezed between the north walls of the old city and the harbor is Sa Penya, a long labyrinth of stone-paved streets that offer some of the city's best offbeat shopping, snacking, and exploring. The tourist information office on Vara de Rey has a useful map of walks through the old city.

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.

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.

Dating from Roman times, the Galician city of Vigo has a fine natural harbour and is renowned as the biggest fishing port in the world. It is also full of history - it was in this fjord-like quay that the English and Dutch defeated the French and Spanish fleets in 1702. Today, the attractive marinas stand in contrast to the industrialised areas of the city, while further exploration will reveal the characteristic 17th-century architecture and attractive countryside beyond. The charming Old Town is a delight, with its labyrinth of winding narrow streets and shaded squares. Nearby is the Cathedral city of Tui, and further to the north is the pilgrimage centre of Santiago de Compostela, which can be reached by car in approximately 1¼ hours.
