Spain’s third city is a dazzling destination that combines historic architecture, cutting edge design and an inviting stretch of beach. Don’t miss the futuristic City of Arts and Sciences, designed by local architect Santiago Calatrava, or the old riverbed, now a delightful park.

Cartagena was founded by the Carthaginians around 227 BC, who named it after their home city in North Africa. These days the city is best known for its well-preserved Roman theatre, which was remarkably only discovered in 1987, in spite of its location in the centre of town.

Málaga boasts plenty of chic restaurants and bars where you can ease into the rhythms of life in southern Spain, before exploring sights including the intriguing, unfinished Gothic cathedral, and a museum devoted to the city's most famous son, Pablo Picasso.

Sovereignty of ‘The Rock’ has been a thorny issue ever since Gibraltar was ceded to Britain in 1713, though on the ground it’s clear where most locals’ sympathies lie. Gibraltar is often described as ‘more British than Britain’, a curious enclave of red postboxes, double decker buses and chip shops.

The crumbling, sun-baked seafront city of Cádiz is said to be the oldest continuously inhabited settlement in the western world, founded by the Phoenicians around 1100 BC. Although the city lacks any obvious landmarks, it’s rich in atmosphere, and plays host to one of Spain’s most colourful carnivals.

After years of neglect, Tangier is finally being restored to its former glory as a cosmopolitan crossroads between Europe and Africa. The Moroccan government has invested heavily in modern infrastructure, while the spruced up medina shines with a new-found cultural dynamism.

Bustling and modern, fizzing with industry and commerce, Casablanca is often overlooked in favour of Morocco’s better known tourist draws. But then this is part of its appeal: it’s an authentic and unvarnished city, and it’s also home to the spectacular modernist architecture of the Hassan II Mosque.
