Tipon is an Inca royal estate and hydraulic complex 23 kilometres southeast of Cusco at 3,560 metres elevation. The site is attributed to the reign of Viracocha or his son Pachacuti in the early 15th century and is celebrated for its sophisticated water engineering — a network of stepped agricultural terraces, ceremonial fountains, and stone-lined irrigation channels fed by a perennial spring at the head of the basin. The American Society of Civil Engineers designated Tipon an International Historic Civil Engineering Landmark in 2006 in recognition of its hydraulic design. The principal terraces extend across 12 levels with intricately fitted retaining walls and flush stair flights inset into the courses. The Intihuatana sector at the upper edge of the complex includes ceremonial buildings of fine ashlar masonry. Active water still flows through every original channel, splitting and rejoining at hand-cut diversion stones precisely as the Inca builders intended.
The ceremonial fountains run year-round at consistent volume.
