Once a wine warehouse, Azkuna Zentroa is now one of Bilbao’s main cultural spaces. Inside you’ll find cinemas, galleries, a library, a gym, and even a rooftop swimming pool with a glass floor you can look up through from the atrium below. Philippe Starck, a French industrial architect, redesigned the building, adding 43 columns, each with a unique style, and open spaces that make the building an attraction in its own right. The venue’s programme ranges from art exhibitions and talks to film screenings and concerts.

The Museum of Fine Arts is definitely a not-to-be-missed attraction, even just for the stunning white building where the museum is set up. Named after the famous sculptor Denys Puech, who lived in the area in the late 19th and early 20th century, this has been a meeting place for modern and contemporary creations since 1989.

The Cíes Islands, just off the coast of Vigo, are home to one of the world's finest beaches (Rodas Beach), and are easily accessible by sea. Only 2,200 visitors per day are allowed on the islands, so do reserve your spot in advance if traveling during high season or at the weekends.

Built from the late 14th to the 15th centuries, the Santiago Cathedral is the city’s oldest major church, dedicated to Saint James (Santiago), Bilbao's patron saint. The building features a mix of different styles: its core is Gothic (nave, vault, cloister), a grand Renaissance portico was added in the 1500s, while much of the façade and tower with spire were rebuilt in a neo-Gothic style in the late 1800s by Severino de Achúcarro. Inside, you’ll see three naves, several side chapels, the Gothic cloister accessible via the Door of the Angel ('Puerta del Ángel'), and beyond the main altar, there’s an ambulatory with chapels. Floods in 1983 caused damage, but the cathedral was restored and reopened around 2000.
