Lasers reveal 15th-century fortified Zapotec city in Mexico

In the 15th and 14th centuries, some of the Zapotec migrated to the southerly Isthmus of Tehuantepec, where they established Guiengola close to the Pacific Ocean. Its existence was discussed in historical Spanish texts and excavators have actually performed job at the website, the city’s complete level was not recognized till researchers utilized lidar to map it.

“In the most fortified markets of the site, which are closest to the river, we have found what can be buildups of round pebbles and small river rocks by the thousands,” Celis claimed, noting that they can be from the battle. The Aztecs, among other teams, used stones that were hurled with slings in war.

To get more information regarding a 15th-century city called Guiengola, a group led by Pedro Guillermo Ramón Celis, a post-doctoral other at McGill University in Canada, used lidar to map out the website in December 2022. The results were released by Celis on Nov. 8, 2024, in the journal Ancient Mesoamerica.

The Zapotecs are an Indigenous people that continue to grow in Mexico. In the 14th and 15th centuries, some of the Zapotec moved to the southerly Isthmus of Tehuantepec, where they developed Guiengola near the Pacific Sea.

The strategy, called lidar (light discovery and ranging), works by having an equipment aboard an aircraft send out millions of laser pulses towards the ground and after that determining for how long it considers the lasers to get better. With this information, researchers can map the topography of the land.

There is a river that runs near the city.

They likewise recognized a complex that measures about 148 feet (45 meters) from eastern to west and 164 feet (50 m) from north to south. “I propose that this complex was the home and catbird seat of Guiengola,” Celis wrote in the journal article.
