Fodor's Expert Review Casa Botines

This Gaudí masterpiece, which housed a bank until 2017, is now an excellent museum dedicated to the Moderniste architect. Under the conical spires and behind the squamous facade are more than 5,000 works of art spanning eight centuries by such renowned masters as Sorolla, Madrazo, Gutiérrez, and Solana. Given that this is the largest of Gaudí's buildings to be opened as a museum, it's worth the extra few euros for a guided tour in English.
