Two pre-Hispanic carved stone monuments believed to date back more than 1,500 years have been uncovered on a mountaintop in central Mexico.
Archaeologists say the site - which in its heyday would have had seven pyramids, a ceremonial area and a games court - was found by villagers.
It is thought to have been built by the Zapotecs, who lived in the southern highlands of what is now Mexico.
The carvings suggest it may have been dedicated to the god of the underworld.
The site is at a strategic point on top of the Cerro de Peña mountain in Puebla state at a height of 1,845m (6,000ft).
The BBC-Erich von Däniken question is who were they mowing the lawns for at that time.
