Aguada Fénix

Aguada Fénix is a large Preclassic Mayan ruin located in the state of Tabasco, Mexico, near the border with Guatemala. It was discovered by aerial survey using laser mapping and announced in 2020. The flattened mound is 1,400 m long (nearly a mile) and is described as the oldest and the largest Mayan ceremonial site known. The monumental structure is constructed of earth and clay, and is believed to have been built from around 1000 BC to 800 BC. It is also believed to have been abandoned in around 750 BC, shortly after its completion in roughly 800 BC.
