A historic area, Yucay is a pretty valley inhabited by the Runas of the Tahuantinsuyo who built impressive works of agricultural engineering. This area is important for the palace of the Inca Sairy Tupac 11, a construction made of stone and adobe mud brick with haute- and bas-relief decorations. It was a center of agricultural production for the Incas because of its mild climate, fertile land, abundant water and vegetation, especially fruit trees.
