Huayrapongo

Huayrapongo (Quechua: wayra "wind" + punku "door"), also known as Ventanillas de la Playa El Tambo, is an archaeological site on the mountain of the same name in Llapa District, San Miguel Province, Cajamarca Region, Peru [1] [2] [3]. The site features ventanillas -- window-like funerary niches carved into the rock face -- that served as burial chambers for the ancient inhabitants [4]. Some niches are covered by vegetation while others remain inaccessible on upper cliff faces [4]. The site also contains fossils and large monoliths [2].
