The IRA operates in two historic buildings owned by the PUCP located in the centre of Lima: the
Casona Riva-Agüero (headquarters) and the '''Casona O'Higgins'''.
Casona Riva-Agüero The
Casona Riva-Agüero, also known as the
Casa Ramírez de Arellano, was built in 1760 by the Spanish colonel Domingo Ramírez de Arellano y Martínez de Tejada, to be used as a family home by him and his descendants. It is considered one of the main attractions of the
historic centre of Lima and one of the best preserved ancient buildings in the city. It was owned by the Marquises of Montealegre de Aulestia and donated to the PUCP by the last of his descendants:
José de la Riva-Agüero y Osma. In addition to classrooms and offices, there is a library, a historical archive known as the
Riva-Agüero Historical Archive (), and the Museum of Popular Arts and Traditions. The archive houses the documents inherited by Riva-Agüero from his ancestors, as well as those produced during his lifetime.
Casona O'Higgins The original construction of the Casona O'Higgins dates back to the beginning of the 16th century. The construction was modified over time depending on the use given to the property. The Chilean hero
Bernardo O'Higgins spent his adolescence in the building, during the government of his father:
Ambrosio O'Higgins,
viceroy of Peru. In 1830, during his exile, he rented the house, which he occupied with his family until his death in 1842. The house became property of the PUCP as part of the legacy left by Riva-Agüero. The archeology section and the Josefina Ramos de Cox museum operate there. ==See also==
