Converted in 1994 by the Fundación César Manrique into a sleek, contemporary art museum and restaurant, the Castillo de San José was built in the 18th century to deal with pirates and provide unemployed locals with a public-works job scheme. Today it houses one of the most important collections of modern art in the Canaries. Aside from a couple of early works by Manrique himself, artists such as Miró, Millares, Rivera, Sempere and Tápies are on show.
