A vital Inca road once snaked its way up the canyon that enters the Sacred Valley at PISAC , and the ruined citadel which sits at the entrance to the gorge controlled a route connecting the Inca empire with Paucartambo, on the borders of the eastern jungle. Nowadays, less than an hour by bus from Cusco, the village is best known for its good Tuesday, Thursday and Sunday morning market , held on the town's main square, the Plaza Constitución, where you can buy hand-painted ceramic beads and pick up the occasional bargain.
