What is good to know if travelling to San Juan?- One venue for Puerto Rico’s Latino chic is surprising — the Museo de Arte. Some Puerto Ricans come to the art museum at least once a week, and not just for its fine collection of Puerto Rican art. They also come for productions in the 400-seat theatre. And trendy locals can be seen strolling the museum’s lovely five-acre garden.
- San Juan has done a great job of adapting old buildings to new uses. La Princesa, for centuries one of the most feared prisons in the Caribbean, now houses the Puerto Rico Tourism Company. It features an exhibit of art by Puerto Ricans, which is free to the public.
- Another example of reuse is the 19th-century insane asylum, the Antiguo Manicomio Insular, which is now the home of the Puerto Rican Academy of Fine Arts, with its lovely courtyard fountains surrounded by elegant iron fences.
