Saqsaywaman, Archaeological site in Cuzco, Peru

Saqsaywaman is an archaeological site in Cusco, Peru, sitting at 3,701 meters above sea level and known for its massive stone walls built with interlocking blocks. The stones fit together so tightly that no mortar was needed to hold them in place.

Construction started in the 15th century under Inca ruler Pachacuti and continued for three generations until the complex was finished. Later, in the 16th century, Spanish invaders removed many stones to build churches and houses in the city below.

The Quechua name Saksaywaman means "fortress of the royal falcon or hawk"; Spanish sources also gloss it as "satisfied falcon." The site hosts the annual Inti Raymi sun festival and the Warachikuy initiation rites, when dancers and musicians gather on the esplanade.

Access is by foot from the center of Cusco or by vehicle along a paved road that climbs the hillside. Visitors should plan enough time to explore the sprawling terraces and walls at their own pace.

Some of the largest blocks weigh over 120 tons and were moved into place without wheels or pack animals. The Inca likely transported these stones using wooden rollers and hundreds of workers over several kilometers.
