It consists of a circular structure (22 m in diameter by 2.5 m in height) on which rests a quadrangular room. It presents a narrow stairway to the north and its eastern façade extends towards a circular plaza. Burial 14 was located in this complex, associated with the second construction stage and a possible ritual sacrifice event, distinguishable by the abundant ceramics. The first construction stage had walls decorated with red paint. Due to its design, it may have been a shrine to Ehecatl, god of the wind.
