Experts believe the 7,000-year-old circular stone structures were once houses, complete with doorways and roofs in Saudi Arabia
Archaeologists have excavated eight ancient standing stone circles in Saudi Arabia that they say were used as houses.
Eight of the 345 stone circles identified by aerial surveys in the Harrat Uwayrid lava field in Saudi Arabia have been analyzed by researchers from the University of Western Australia and the University of Sydney, who suggest that the structures may have been roofed and served as dwellings.
These findings were published in the scientific journal Levant by a research team led by archaeologist Jane McMahon from the University of Sydney. The study examined 431 standing stone circles at various sites in Harrat Uwayrid in AlUla, with 52 undergoing field surveys and 11 being excavated.
This study, supervised by the Royal Commission for AlUla (RCU), reveals that the regions inhabitants were more stable and advanced than previously believed.
The circles date back around 7,000 years and have the remains of stone walls and at least one doorway.

These dwellings consisted of vertically erected stone slabs with diameters ranging from four to eight meters. The outer circumference had two rows of stone slabs, likely used as foundations for wooden columns, possibly made of Acacia, supporting the roof
