The Incan site of Sacsayhuaman

Situated near the old city of Cuzco, Sacsayhuaman is an Incan walled complex. The walls, most experts believe, were built for fortification, though some historians believe they form the head of the Puma, a sacred Incan animal whose shape can be seen from the air. The precision of the stonework is incredible and, much like the work at Machu Picchu, the stones fit together so well that the thin blade of a knife cannot slip between the stones.

This Incan site is best known for its “chincanas,” underground passages that connect the complex with the city of Cuzco. Sacsayhuaman is also the site of the annual Incan festival that celebrates the coming of the winter solstice.
