Triadic pyramid

Triadic pyramids were an innovation of the Preclassic Maya civilization consisting of a dominant structure flanked by two smaller inward-facing buildings, all mounted upon a single basal platform. The largest known triadic pyramid was built at El Mirador in the Petén Basin of Guatemala; it covers an area six times as large as that covered by Tikal Temple IV, which is the largest pyramid at that city. The three superstructures all have stairways leading up from the central plaza on top of the basal platform. Triadic pyramid structures are found at early cities in the Maya lowlands.
