The Isamatul Pyramid was built in three stages. In the first stage, it was a multi-level pedestal foundation with a slight slope and curved corners on each side. In the second stage of construction, the first building was completely enclosed, the corners were rounded, and vertical walls were erected. It is believed to have had only one staircase on the western side, which was later restored. Its construction may be dated to the years 700-850 AD. The third stage of construction was approximately between 950-1150 AD; the only remaining part from this phase is a large pedestal over 100 meters long, with a staircase on the side.
Regarding the historical traditions of this site, the Isamatul Pyramid was dedicated to the god Zamna, and it is said that a large number of pilgrims came from distant places to ask him for favors. Zamna was the high priest of the Itza people, the wisest person of the Maya culture, knowledgeable in sciences and arts. During excavations, some masks bearing the face of Zamna were found; they remained after the pyramid was looted and dismantled for building materials. This is one of the key structures of the ancient Isamal plaza, in which three construction stages have been identified.
