Holmul is a pre-Columbian archaeological site of the Maya civilization located in the northeastern Petén Basin region in Guatemala near the modern-day border with Belize.
The initial work by Merwin at Holmul (later expanded by George Clapp Vaillant) produced the first stratigraphic ceramic sequence to be defined at a Maya region site.
[2] However, the results of this Peabody Museum expedition were not formally published until some twenty years afterwards, and subsequently the site remained relatively little-studied.
Excavation and research at Holmul resumed only in the year 2000, as an archaeological group from Boston University, organized by Dr. Francisco Estrada Belli, began to explore the site.
Below the frieze runs a long inscription from which it appears that the construction (which contains a staircase burial) was commissioned by king Ajwosaj of Naranjo, a city on the Holmul River.
