Chankillo: Ancient observatory
Archaeological evidence indicates that Chankillo may be the earliest known astronomical observatory in the Americas. Built over 2,300 years ago, the site features a plaza, Thirteen Towers that align on a ridge, and a Fortified Temple surrounded by barricades and defensive walls with false entrances to deter unwelcome visitors.
In July 2021, the Chankillo Archaeoastronomical Complex was inscribed on the UNESCO World Heritage List as a masterpiece of human creative genius and an outstanding example of a type of building, architectural or technological ensemble or landscape which illustrates a significant stage in human history.
