Buena Vista, Peru
From Wikipedia, the free encyclopedia
Buena Vista is the 20-acre site of an archaeological dig north of Lima, Peru.
In May, 2006, archeologist Robert Benfer of the University of Missouri announced the discovery of a 4200 y.o. observatory discovered on the site, located in the Rio Chillon Valley. At the foot of the Peruvian Andes, with structures that mark the summer and winter solstices, it is the oldest known observatory in the Americas.
The site was first inhabited by an unknown pre-ceramic culture (archaeologists simply call them the Andeans) over 10,000 years ago.
The observatory is located atop a small pyramid which is part of a temple. Radiocarbon dating of materials from the temple dates its use to 2200 B.C.E.
