Located among the private suger cane fields near the village of San Pablo, Nohmul was a major ceremonial center.

First occupied in the Pre-Classic around 350 B.C. and 250 A.D. the site declined in the Early Classic period becoming nothing more than a ghost town.  But then around the late classic period the population went up again.  At the height of its powers Nohmul was the seat of government for the surrounding eight miles.  During the post classic period it was ruled by a people who were not of local origin.

Thomas Gann first discovered Nohmul in 1897.  He returned to excavate between 1908 & 1909, 1911 & 1912, and again with his wife in 1935 and 1936.  Most of the artefacts discovered were given to the British Museum.  One structure was partially destroyed for road fill during a construction of a road in 1940 and three burial chambers were uncovered, one was looted before authorities got to the scene.  Norman Hammond excavated the site in 1973, 1974, 1978, and began a large-scale excavation in 1982.

Located on privately owned suger field behind San Pablo, the entrance is one mile along the road west of the village.
