This building forms the eastern side of the South Plaza and despite being the largest of it, it is small next to structures 1, 2 and 3 of the central plaza.

It is a rectangular base whose walls are slightly sloping. As a decorative element, it has in the upper part a cornice formed by a band of stones that protrude from the level of the wall; the stones are very large, some are up to a meter long. The corners of the basement are rounded, a rare feature in northern Yucatan architecture. This indicates some relationship with the Petén region, in Guatemala.

Structure 10 is 43 meters long, 30 meters wide, and approximately 5 meters high. In its upper part there are three more structures; two of them are low-rise platforms with no construction on top. There is also a small vaulted temple with very thick walls and whose interior space is occupied by an altar.

Due to its architectural characteristics, it can be associated with the "Miniature Temples" of the Eastern Coast of Quintana Roo.

Although the basement corresponds to the Late Classic (700 - 1000 AD), the upper structures were built until the Postclassic (1200 - 1542 AD).
