Museo de Arte de Puerto Rico. One of the Caribbean's biggest museums, this beautiful neoclassical building was once the San Juan Municipal Hospital. The collection of Puerto Rican art starts with the colonial era, when most art was commissioned for churches. Works by José Campeche, the island's first great painter, include his masterpiece, Immaculate Conception, finished in 1794. Also well represented is Francisco Oller y Cestero, who was the first to move beyond religious subjects to paint local scenes. Another room has works by artists inspired by Oller. The original building, built in the 1920s, proved too small to house the collection; a newer east wing is dominated by a five-story stained-glass window by local artist Eric Tabales. The museum also has a beautiful garden with native flora and a 400-seat theater with a remarkable hand-crocheted lace curtain. 299 Av.
