Casa Hacienda Punchauca, Hacienda house in Carabayllo, Lima, Peru

Casa Hacienda Punchauca is a viceregal hacienda built on a huaca called Punchau, at km 25.5 of the Carretera a Canta in Carabayllo. Its bearing walls of adobe rest on stone-and-lime footings with brick over-footings, and a two-flight stair converges on the covered gallery. The neoclassical building is divided into a barrel-vaulted chapel, a session hall and an annex room, with smooth columns before the main hall.

Casa Hacienda Punchauca was built in the viceregal period on a huaca called Punchau, at km 25.5 of the Carabayllo road to Canta. On 2 June 1821 its rooms hosted the peace talks between General José de San Martín and viceroy José de la Serna during the Peruvian independence war.

The hacienda's name comes from the huaca Punchau, the pre-Hispanic site beneath it. Its neoclassical layout groups a barrel-vaulted chapel, a session hall and an annex room around a covered gallery reached by a two-flight stair converging at its centre. Smooth columns stand before the main hall, the sacristy and the rooms.

The property sits along the main highway connecting Lima to the mountain towns inland and is accessible by road. Visitors should check accessibility and tour availability before planning their visit to the site.

The building was constructed directly over the remains of a pre-Hispanic sacred site, making it a rare example of colonial-era layering of old and new. This overlapping of religious spaces reveals how power was expressed through architecture and land use.
