The Oldest Adobe Structures in Peru Uncovered

November 27, 2021

Archaeologists in Peru have uncovered monumental adobe structures At the Los Moteros site in the desert region of the northern coast or Peru. The structures are dated to 5,100-5,500 years ago. Carol-Supe culture structures. This was the starting point for the evolution of complex adobe construction in Peru stretching over thousands of years. The Los Moteros structures were found by radar. And only adobe was used with no additions for stability. The clay deposits were in a place probably created by El Niño flooding.

Radar was used to detect an underground structure at the Los Morteros archaeological site measuring 10 meters (33 feet) long, seven meters wide and two meters tall. After it was unearthed, Mauricio and her colleagues were astounded to see that the walls were made of adobe, which was unprecedented for that era.

The archaeologists observed that the adobe bricks were made exclusively of clay and that no other material had been mixed in to provide greater stability, a clear indication that the architectural technique was in its very early stages.

An analysis of the bricks’ composition also showed that the adobes were cut from natural clay deposits located near the mouth of the Chao River and likely created by El Niño flooding.

The research was published in the Proceedings of the National Academy of Sciences (PNAS)
