Incallajta, is an ancient stone citadel located in the outlying southeastern quarter of the once extense Inca Empire. Its strategic importance as an advanced warrior outpost and because being situated in a concealed valley, adjacent to fertile regions of Cochabamba Department, gave it a significant role as an agricultural center. The fundamental function of the citadel though, in its expansive years (circa 1450), was the containment of the warlike Amazonic Chiriguanos, occasional invaders to the higher valleys. Its elevation stands at 2680 m. The San Simon University Archaeological Museum in Cochabamba will be visited, to follow up on important facts on the citadel, as well as viewing artifacts of the Inca culture.
