Recent discoveries include the oldest and largest Maya ceremonial structure, which was uncovered at the archaeological site of Aguada Fénix in Tabasco, Mexico in 2020. The long, rectangular elevated platform measures 1,400m (4,593ft) in length and 10-15m (33-49ft) in height. It was built from clay and earth between 1,000 to 800 BCE and was likely used for ceremonial rituals.
