About Guiengola

Guiengola (Isthmus Zapotec for "big stone") is a late Zapotec city spread over a rugged limestone mountain above the Tehuantepec River, about 12 km north-west of Tehuantepec in a straight line and just off Highway 190 to Oaxaca. It was occupied from around 1350 until the Spanish conquest. Tradition and early Spanish accounts make it the stronghold where the Zapotec lord Cosijoeza held out against the Aztec ruler Ahuizotl in the 1490s; the war ended with Cosijoeza marrying one of Ahuizotl's daughters, and their son Cosijopii became the last Zapotec king of Tehuantepec.

For a long time Guiengola was described as a fortress. A lidar survey led by the archaeologist Pedro Guillermo Ramón Celis between 2018 and 2023, published in Ancient Mesoamerica in 2024, showed something larger: a planned city of about 360 hectares with more than 1,100 structures, around 4 km of defensive walls, roads, temples, ball courts and separate districts for the elite and for commoners. Earlier explorers included Eduard Seler and, in the 20th century, David Peterson and Thomas MacDougall.

The ceremonial core sits on a levelled terrace of roughly 150 by 200 m between two rocky peaks. It holds an east and a west pyramid, each of three stepped bodies, a ball court with two round rooms, and, 200 m to the south-east, a palace complex of 64 rooms. Elsewhere there are robbed family tombs, cross-shaped tombs, caves with rock paintings and stretches of wall. Nothing has been rebuilt, and dry tropical forest covers much of it; the final approach is on foot, partly through a narrow passage between tall rocks, and from the top the view takes in the valley and, on clear days, the Pacific.
