Museo de Bellas Artes de Valencia

One of Spain's most important art museums, often ranked second only to the Prado. The strongest holdings are in Valencian masters like Joaquín Sorolla and José de Ribera, with additional works by Velázquez, El Greco and Goya. It's housed in a 17th-century former seminary just across the Turia from the Old Town, and admission is free. We didn't make it there, but it's supposed to be great.
