With so much to see and do, we've narrowed it down to 8 cities that everyone should visit in Spain.

Barcelona is a Spanish city that has it all: beautiful Mediterranean beaches, fascinating architecture and a lively restaurant and shopping scene. Unique to Barcelona are the Modernista buildings designed by architect and genius Antoni Gaudí, the most impressive of which is the unfinished Sagrada Família church and its fairytale-like spires. Head to Parc Güell, now an UNESCO World Heritage site, to see more of Gaudí's works and for stunning views across Barcelona's terracotta rooftops.

Nestled at the base of the snow-capped Sierra Nevada mountains in southern Spain, the ancient city of Granada was the last stronghold of Islamic Spain during the Reconquista. Today, the city is well-loved for its intricately-formed mosaics, Mudéjar-style fountains and grand horseshoe arches. Overlooking the city on a tree-lined hilltop is The Alhambra, a breathtaking Moorish palace-complex that houses some of the best preserved Islamic art and architecture in the world. The fortress also offers amazing views of the city's winding cobbled streets and of the Spanish countryside and hills that lay beyond.

Are you a bit of a beach bum? San Sebastián, a picturesque city on the Basque Country coast, has some of the best beaches in Europe. Playa de la Concha, a beautiful, shell-shaped cove is popular with those wanting to kick back, relax, and catch a tan, while the nearby Zurriola beach is great for surfing and other water sports. The city is also every foodie's dream with many world-class Michelin-starred restaurants lining its seafront promenades. But it's possible to eat on a budget too. Meander through the city's cobblestoned old town and take your pick from vibrant pintxo bars offering affordable bite-sized treats.

Discover Seville, the quintessential Andalusian city. By day, take a stroll through the Old Town, whose labyrinthine streets are too narrow for most cars to safely navigate, or pay a visit to the Alcázar, an ornately-decorated Moorish palace with luxurious gardens and courtyards. You may recognise the sprawling palace-complex from season five of Game of Thrones as it was the primary filming location for the fictional city of Dorne and the Water Gardens. By night, get swept away by one of Seville's famous flamenco shows at Los Gallos or El Arenal, two of Seville's most popular and liveliest flamenco tablaos.
