7 Best Places to Visit in Spain

Spain draws more international visitors than almost any other country, spanning Moorish palaces in the south, a Mediterranean party island, and a Basque coastline built around food. Here are seven of its most iconic destinations, from major cities to standalone landmarks.

1. Sagrada Família, Barcelona

Antoni Gaudí's unfinished basilica has been under construction since 1882 and remains Barcelona's defining landmark. Its soaring stone towers and intricate facades earned it UNESCO World Heritage status as one of Gaudí's works, and the interior's forest-like columns and stained glass are as striking as the exterior.

2. The Alhambra, Granada

This hilltop palace and fortress complex was built mainly during the 13th and 14th centuries under the Nasrid dynasty, Granada's last Muslim rulers. Its horseshoe arches, carved stucco, and reflecting pools in the Court of the Lions make it one of the finest surviving examples of Islamic architecture in Europe, and it's a UNESCO World Heritage Site along with the adjoining Generalife gardens.

3. Madrid

Spain's capital centers on the Prado Museum, home to masterworks by Velázquez and Goya, and the vast Retiro Park just behind it. The Puerta del Sol marks the city's symbolic center, and Madrid's mix of grand 19th-century boulevards and narrow old-town streets make it easy to explore on foot between sights.

4. Seville

Seville's Real Alcázar, a royal palace still used by the Spanish royal family today, sits beside Seville Cathedral, the largest Gothic cathedral in the world and the burial place of Christopher Columbus. Both are UNESCO World Heritage Sites, and the city is widely considered the birthplace of flamenco.

5. San Sebastián

Set on the Basque coast, San Sebastián curves around the shell-shaped La Concha Bay, regularly ranked among Europe's best urban beaches. The city is also renowned for its pintxos bars — Basque-style small plates served across the old town — and holds one of the highest concentrations of Michelin-starred restaurants per capita in the world.

6. Toledo

Perched on a gorge above the Tagus River, Toledo served as Spain's capital until the 16th century and is known as the 'City of Three Cultures' for its layered Christian, Muslim, and Jewish heritage. The walled old town, a UNESCO World Heritage Site, includes the Gothic Toledo Cathedral and several works by the painter El Greco, who lived there for much of his life.

7. Ibiza

This Balearic island is best known internationally for its nightlife, with some of the world's most famous clubs, but its old town, Dalt Vila, is a walled UNESCO World Heritage Site dating back over 2,500 years. Beyond the party scene, Ibiza's coastline has quieter coves and beaches on its northern and western sides.

Staying connected while you travel
