Calakmul was located in the Yucatan Peninsula tropical forest of the Tierras Bajas, 30 km north of the Guatelmala border. Cyrus Longworth Lundell discovered the site in 1931 and named it Calakmul, based on the Maya words for "two adjacent pyramids".
Calakmul was occupied from Middle Preclassic to Postclassic times. It was the administrative center of an area about 8000 sq km and a population to match, requiring the development of a sophisticated system to supply water, especially during the dry periods.
The first dated inscription from Calakmul is stela 114 from A.D. 431 and found in 1994. It commemorates a Calakmul monarch.
