It may not be a typical museum, but San Sebastián’s Aquarium is one of its most popular sights, attracting 300,000 visitors per year. Located in the Old Town, it’s housed in a historic building, built in 1928. Explore its two floors to learn all about the city’s maritime heritage and native marine life, and don’t miss its huge tanks – one filled with species from the Bay of Biscay and the other with tropical life. There’s also a huge skeleton of a North Atlantic right whale.
