It is currently housed in the former Ballajá Barracks, built between 1854 and 1864 as one of the last major architectural projects of the Spanish colonial rule over the island before it was annexed by the United States in 1898. Initially, when Puerto Rico was annexed by the United States, the federal government paid the Catholic Church for this property, among others in the area. Ownership of the property, claimed by the Catholic Church, was not a straightforward matter and had to be resolved by the Supreme Court. The Government of Puerto Rico acquired the building in 1976 through a transfer from the Government of the United States with the commitment of restoring it and using it for cultural, educative, and touristic purposes. In 1986, a reform plan for the San Juan Historic Zone was sketched and the building was restored from 1990 to 1993.
