Chankillo, Archaeological site in Casma, Peru.

The Chankillo complex spans four square kilometers in the Peruvian coastal desert, featuring thirteen stone towers arranged in a straight line along a ridge.

Built around 400 BC, the stone structures of Chankillo served as an astronomical observatory to track solar movements through carefully positioned towers.

The thirteen towers demonstrate the advanced knowledge of astronomy and mathematics developed by ancient Peruvian civilizations before the Inca Empire.

Visitors access the site through guided tours departing from Casma town, with the dry season from April to October offering the most favorable conditions.

The towers create precise solar alignments during solstices and equinoxes, marking seasonal changes through shadows cast upon specific observation points.
