Ballajá Barracks, Military museum in Old San Juan, Puerto Rico
The three-story Ballajá Barracks spans 7,700 square meters with a central courtyard and features Gothic vaulted ceilings above the main staircase.
Constructed between 1854 and 1864 as Spain's final major project in the Americas, the barracks housed Spanish troops until the Spanish-American War in 1898.
The Museo de las Américas, established in 1992 on the second floor, presents exhibitions about the history and traditions of the American continent.
The building contains a dance school, coffee shop, restaurant, movie theatre, and offices of the Puerto Rican Academy of the Spanish Language.
The structure incorporates a 24,000-square-foot green roof with an artificial wetland system that manages stormwater and supports sustainable irrigation.
