Casa Hacienda Punchauca

The Casa Hacienda Santiago de Punchauca is a historic building at the 25th kilometre of the Lima–Canta Highway in Carabayllo District, Lima, Peru. The viceregal building was built over a Huaca and is part of the Cultural heritage of Peru since 1980.

History
Named after its original owner and once owned by Nicolás de Ribera and Hipólito Unanue, it is the location of the conference of the same name between José de San Martín and José de la Serna, 1st Count of the Andes. Under the military government of Juan Velasco Alvarado, the building—already in a poor state, as its reconstruction was promoted by Raúl Porras Barrenechea—was expropriated as a consequence of the Peruvian Agrarian Reform.
