This nonprofit foundation serves many functions: museum, performance space, dance and music school, and archive dedicated to preserving the contributions Puerto Ricans have made to music, dance, television, theater, film, and other culture. In a 300-year-old building once used by the Spanish as a meterological lookout, you can visit a rotating exhibition, come in the evening to hear live Latin music, or take a bomba or plena dance class. A small store sells music by Puerto Ricans in every genre, from classical to salsa. Signed posters from El Gran Combo, Tito Puente, and Willie Colon—as well as Ricky Martin's platinum record—line the walls. Check the website or call ahead for the performance schedule.
