Chankillo was built over 2,300 years ago in the coastal desert of Peru. Constructed from cut stone, it includes a fortified temple, a plaza, and 13 towers. Chankillo is unique because its towers are situated between two observation platforms and these markers span the entire annual rising and setting arcs of the sun, which shift north and south along the horizon gradually over the course of a year. Archaeological evidence indicates that Chankillo may be the earliest known astronomical observatory in the Americas. Travel to Peru with Far Horizons!
