3000 year old ancient ceremonial pyramid unveiled in Central Mexico

Recent archaeological excavations in central Mexico's Puebla state reveal stone pyramids used by indigenous communities for ceremonies over 3,000 years ago. The site's astronomical significance for monitoring agriculture was confirmed. Despite damage, artifacts including burned ceramics were found. The main pyramid was aligned with Canopus. After abandonment, locals returned to honor ancestors. Further research is planned, with the site remaining closed to the public.
