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.

Melilla is a post-colonial oddity, a Spanish enclave on the north coast of Morocco. The city is a fascinating blend of Spanish, Moorish and Berber influences, with an impressive collection of modernist buildings, plenty of bustling tapas bars and an atmospheric walled old town, the Medina Sidonia.

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.
