Distribution in Mesoamerica

E-Group structures are found at a number of sites across the Maya area, particularly in the lowlands region. The oldest-known E-Groups coincide with the earliest Maya ceremonial sites of the Preclassic period, indicative of the central role played by astronomical and administrative concerns in the very beginnings of Maya ceremonial construction and planning. The oldest documented E-Group is found at the site of Seibal. Construction of E-groups continues on through the Classic period, with examples of these including the Lost World Pyramid at
