Huaca Casa Rosada, Archaeological site in San Miguel, Peru

Huaca Casa Rosada is an archaeological site in San Miguel with a square structure measuring roughly 36 meters on each side. The construction uses adobe bricks and rammed earth materials layered through different periods of occupation.

The site dates to the Intermediate period and continued in use through the Inca era, later covered by Spanish colonial structures. During the Republican phase, additional buildings were constructed atop the pre-Hispanic foundations.

The name comes from the Casa Rosada, a single-storey Republican house of quincha and wood built on the huaca's filled adobe platform; its exterior was finished with a mud cake painted pink. Its beams and posts, probably white and mulatto oak from Guayaquil, were reused as building material during the Pando urbanisation and the house was lost. Since July 2024 residents have cleaned and lit the site for cultural activities.

The site is located in an urban area of Lima between several streets and is accessible on foot. It helps to know the exact address beforehand since the location is not always easily visible from the surrounding area.

Excavations in 1973 and 1974 by the Seminario de Arqueología of the Pontificia Universidad Católica del Perú found French earthenware 5 mm thick, with floral motifs painted in fine blue lines on a white ground, plus green bottles of French wine. Some brown, green and purple glazed ceramics from the site are not found elsewhere in the Pando area.
