Located some 400 kilometers (250 miles) to the north of Lima, sits the Western Hemisphere's oldest known full-service solar observatory, according to a report in Peru's El Comercio newspaper.
The important archaeological discovery contains 13 stone pillars that sit along a coastal mountain side. The observatory, which is believed to be approximately 2,300 years, suggests the existence of a sophisticated culture that used the complex arrangement of the stone pillars and the sun for political and ceremonial purposes.
