About
About Písac (Písaq)
Inca royal estate and agricultural terraces considered among finest Inca ashlar engineering beyond Machu Picchu: Intihuatana (Sun-hitching stone) solstice-gnomon ridge, Qalla Q'asa fortress on mountain spur, Kinsertamayo and Tantamayo gorges with 500+ hillside cemetery tombs pockmarking cliffs (largest pre-Hispanic cemetery), and semicircular Qanchisracay terraces (72 terraces still cultivable) demonstrating Inca hydraulic gradient (1° drainage). Pachacuti’s estate 1440–1480 integrated into Sacred Valley ceque system to Pisac town’s famous colonial market. Part of Sacred Valley Inca landscape.
Why it mattersType-site for Inca terrace hydrology and estate polity of Sacred Valley; megalithic quality rivals Sacsayhuamán but on mountain spur not fortress type.
