Towers point to ancient Sun cult
The oldest solar observatory in the Americas has been found, suggesting the existence of early, sophisticated Sun cults, scientists report.
It comprises of a group of 2,300-year-old structures, known as the Thirteen Towers, which are found in the Chankillo archaeological site, Peru.
The towers span the annual rising and setting arcs of the Sun, providing a solar calendar to mark special dates.
"I was gobsmacked when I saw them for the first time - the array of towers covers the entire solar arc."
The Thirteen Towers of Chankillo run from north to south along the ridge of a low hill within the site; they are relatively well-preserved and each has a pair of inset staircases leading to the summit.
