Sitio arqueológico Pinkuylluna

This guide to Pinkuylluna in Cusco starts with the wind whistling through stone chambers on the cliff above Ollantaytambo, and the Inca engineering that put it there. You'll hear how the emperor Pachacuti's builders raised qollqas, storehouses that used cold mountain air, clay-packed joints and hidden vents to keep grain fresh for years without a single moving part. From there the guide looks up at the cliff face itself, where locals see a giant brooding profile watching over the valley. Best heard standing at the base of the stairway, where the moaning air is loudest.
