Pachat'aqa, Archaeological site near Lake Titicaca in Copacabana Municipality, Bolivia.
Two parallel stone blocks form an astronomical observatory located 600 meters south of Copacabana, with steps leading to multiple structural remains.
Dating back to 1764 BC during the Chiripa culture period, Pachat'aqa served as a center for measuring time and predicting celestial events.
The name Pachat'aqa translates from Aymara language as 'place where time is measured', reflecting its astronomical purpose for ancient Andean societies.
Visitors can reach the site through local transportation from Copacabana, where accommodations and tourist services are readily available.
Mathematical calculations by the Cosmic Physics Institute of Bolivia confirm the site's function as an ancient astronomical center for tracking lunar movements.
