The Casa de Aliaga is a colonial-style building located in the historic centre of Lima, Peru. It was built on a huaca, dating back to May 1536, at the beginning of the founding of the city, and belonged to Conquistador Geronimo de Aliaga. Its current owner is Gonzalo Jorge de Aliaga Ascenzo, VIII Count of San Juan de Lurigancho. It has been continuously inhabited by the same family for seventeen generations over a period of five centuries.
