This structure known by the name of El Castillo, measures 17m., Is the highest on the entire north-central coast of Quintana Roo.

The investigations carried out in the building have made it possible to identify two construction stages. The first one, consisted of three bodies and a temple on its top with two entrances; The main one was oriented towards the west and as the end of its staircase, an altar was erected in which two offerings were deposited with 264 ornamental objects made of green stone or jadeite and snail (beads, muffs, ear flaps, plates, earrings, rings, a flint knife and a clay censer).

The substructure had an entrance on the east side, the frieze located above it, presents as ornamentation two herons made of stucco.

In the second stage, the first temple was covered and two bodies were added, crowned by the double temple that is in sight.

Peculiar feature of this building is the architectural element located on its roof called a hollow circular "tower", on the outside it is adorned with small flat stones as protuberances, similar to the thorns of the trunk of the ceiba (sacred tree of the Mayans ) probably simulate shapes used in some clay censers.
