The Museum of Fine Arts of Bilbao is one of Spain's most important art institutions. Its origins trace back to the first Fine Arts Museum, founded in 1908, and the Museum of Modern Art opened in 1924. These two museums merged in 1945, forming the current institution. The museum's extensive collection spans from the 12th century to contemporary art, featuring masterpieces by renowned artists such as El Greco, Goya, Velázquez, Picasso, and Francis Bacon. Notably, it houses the most significant collection of Basque art, including works by Regoyos, Zuloaga, and Echevarría.

This extravagantly decorated clandestine church built centuries ago when Catholicism was considered a crime is hidden in plain sight behind an unassuming front door in the city centre. Those walking down Juffrouw Idastraat would never imagine that within one of the typical terraced houses lies the enormous Parish of Saints James and Augustine where Catholics used to practice their faith in secret. Nobody is quite sure who built the church, but the stunning baroque plastering seems to suggest that it was the famous architect and artist Daniel Marot or one of his students. Book a free tour which takes you through the church and the attic to the more recent Bishop’s Chamber which is full of some of the original features and furniture that were used in the 1700s.
