Ceibal's carved stelae are the primary reason specialists rate the site so highly. The Late Classic monuments here are unusually well-preserved — the moist lowland jungle that hastened the decay of unprotected sites elsewhere actually kept many of Ceibal's stelae buried and intact until excavations in the 1960s. The figures depicted show a range of styles: some are standard Maya court compositions, while later monuments show figures with non-Maya headdresses and iconography suggesting outside influence.
The most discussed is Stela 10, dated to around 889 AD, depicting a figure with Gulf Coast or possibly Toltec features — a puzzle that has generated decades of debate about what happened at Ceibal in its final phase. Several stelae remain in situ on the platforms where they were originally erected, while others have been moved under protective shelters. The site's network of jungle paths connects the main plazas, and the combination of stone monuments, towering ceiba trees, and complete absence of crowds makes Ceibal one of the more atmospheric sites in the Petén.
