This site is believed to have been an important ceremonial center for the Pucará culture. Construction started in 80 BC but the complex reached its peak between 250 BC and 380 AD. Two distinct areas stand out: a ceremonial sector and an urban sector. The first is the most important. It’s composed of 9 pyramids, each of a different shape and size, dispersed over an area of approximately 4.2km2. The most prominent is the Pyramid of Kalasaya.
