Sacsayhuaman

On our last morning in Qosqo (Cuzco) I visited Sacsayhuaman, you can see it from the city as the ruin sits on a hill above the city. It is of significance because the Inca´s had a final rebellion against the spanairds here in 1636, 3 years after Pizzarro invaded Cuzco.. however the Spanish attacked in the night and the Inca king was forced to retreat further up the sacred valley to Ollantaytambo. Only about 20% of the site remains as the spanish demolished 3 of the towers and rolled the stones down the hill for use in building the colonial Cuzco city. Some of the stones still remaining like the one above are absolutely massive and weigh a coupla tonnes.. no small feat to move when you have not invented the wheel and have no beasts of burden.. modern scholars cannot realistically quantify how many man hours would have gone into the building of Sacsayhuaman.
