Chullpares de Macaya | Aymara | 1200 to 1300 CE | Sajama National Park, Bolivia | Photo: Jérôme Galland | Chullpas are ancient Aymara funeral towers found across the Altiplano in Peru and Bolivia. Construction method varied with ethnic group: in general, those of the north Altiplano are circular and constructed with stone, while those of the south are rectangular and constructed with adobe. All chullpas have small openings facing east, towards the rising sun.
