The ruins of Ollantaytambo
Only two minutes walk from the center is the temple complex of the Inca era and numerous other buildings. Due to its thick walls, many made in the typical pink sandstone, it is often called Fortaleza. To reach the fortress, you will have to climb a series of steep stairs that lead through the terraces of Pumatallis. At the heart of the fortress is the Temple of the Sun, a building that has never been completed, but with the wall of the Six Monoliths it is clearly the most impressive of Ollantaytambo. The fort includes many other buildings, some even two stories, and water supply systems that still work well.
The area of the temple is the only one made of blocks of carved stone, the rest uses natural stones.
