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.

[1][2] Named after its original owner and once owned by Nicolás de Ribera and Hipólito Unanue,[1] 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.

[3] Under the military government of Juan Velasco Alvarado, the building—already in a poor state,[4] as its reconstruction was promoted by Raúl Porras Barrenechea—was expropriated as a consequence of the Peruvian Agrarian Reform.
