Chankillo

Chankillo is an ancient site in the peruvian desert, near the town of Casma. It is about 2400 years old.

On a hill, there are 13 stone towers. They make it possible to determine the current season at sunrise.

On another hill, there is a fortress-like structure with two central towers and five concentric stone walls.

The gates have door lintels made of Algarrobo wood, which were preserved by the desert climate. By dating the tree-rings, it was possible to determine their age to be 2300 years.
