Lubantuun is a city that dates from the Classic Maya period and the city flourished from AD 730-890. Excavations occurred during the 1920’s and the 1970’s. The architecture of the buildings is unusual from most other Mayan ruins because Lubantuun’s structures are made of large blocks that were laid down without mortar and also that the blocks are black slate instead of the more typical limestone from the area.

The original name of the site remains unknown and the current name is modern in origin and means “place of fallen stones”.
