Casa Blanca Museum (White House Museum), San Juan

Casa Blanca is a house museum located in Old San Juan. This lovely white adobe building is one of the oldest buildings in San Juan. Built in 1521 it served as the first fortification of the San Juan islet and residence for Juan Ponce de Leon, the first governor of Puerto Rico, and his family. Juan Ponce de Leon unfortunately died in an expedition to Florida without ever lived in the house. It was later used as the residence of his descendants, until the mid-18th century. As a fortification it served mostly as a refuge in times of attack from Taino rebels.

The house was built in wood but the original structure was destroyed by fire and rebuilt in stone and masonry. It subsequently was occupied by members of the Spanish army and later by American army commanders. The surrounding gardens were planted by the first American governor of the island in the 19th century. In 1967 the complex was transferred to the government of Puerto Rico and declared a historical monument. In 1981, it was recorded in the Historic American Buildings Survey. The house is a museum of 16th and 17th century artifacts managed by the Institute of Puerto Rican Culture.

The building, walls and gardens are in excellent condition. The plaques on the walls explain the history of each room. The museum charges a small fee ($5) to enter while one can visit the gardens for free.
