The Pigeon Loft Complex consists of three squares with a hierarchical spatial arrangment which get smaller with the increasing height of the platforms to the south finished off with a pyramidal base with two side buildings which together constitute a triadic arrangement. This arrangement forms the focus point of the complex. Each square is bound on four sides by long buildings of multiple rooms known in archeological terms as 'palace-style.' Different levels define three complexes that originate in the sunken courtyard, the quadrangle of the pigeon loft and the triadic complex found in the highest part. The main entrance to the complex is formed by a low, elongated mound located to the north. Access to each level is by means of an outset staircase which is a half vault attached to the facade of a building.
The main access to the complex is from the north, an elongated head-height structure with multiple rooms that seperates the first central square known as the House of the Pigeons or the Pigeon Loft. The facade of this building has nine crests staggered in the form of triangles that resemble pigeon lofts and give their name to both the structure and the complex. The crests are constructed over a row of pillars covered with painted stucco reliefs and figures of characters on pedestals in the center.
This complex, like most of the architecture visible today was built between the third and tenth centure A.D. Its architectural design resembes the acropolis located elsewhere such as Piedras Negras in Guatemala, which are complexes associated with palatial groups that developed administrative and ceremonial activities and, in many cases, housing since they were also the residence of the royal family or groups of noblemen.
