Pampa de los Perros, Archaeological site in Ventanilla, Callao Constitutional Province, Peru

Pampa de los Perros, also called Huaca Rosada, is an archaeological site in the Ventanilla district of Callao, Peru, near the mouth of the Chillón River. It covers 1.5 hectares and consists of a pyramid, a residential area and a circular plaza. Looting and drilling have damaged the site.

This site dates to approximately 3500 to 1800 BCE, a period when early coastal settlements were forming in this region. The occupation reflects the development of ceremonial centers and organized communities during ancient Peru's early times.

The site takes its name from dog figures found in pre-Columbian artifacts discovered during excavations. These animal representations show how important dogs were in both daily life and ritual practices of early coastal inhabitants.

The site is located within an urban area of Ventanilla, so planning ahead and checking local information before visiting is advisable. Access is typically easier during the drier months when ground conditions are more stable.

The sources give no evidence of dog-shaped pottery; the name Pampa de los Perros is documented alongside the alternative name Huaca Rosada, and the site is known for a pyramid, a residential zone and a circular plaza on 1.5 hectares near the Chillón River mouth. Looting and drilling have damaged the structures.
