Satellite radar reveals a 2,600-year-old mudbrick complex buried beneath Buto in the Nile Delta

Egyptian researchers using Sentinel-1 satellite radar and electrical resistivity tomography have mapped a large Saite-period mudbrick structure, about 20 by 25 metres, buried 3 to 6 metres beneath Kom C at Buto (Tell el-Fara'in) in the northwestern Nile Delta, built on a deliberately laid bed of clean sand. The study was published in Acta Geophysica in March 2026 and reported this week; the building's exact purpose is still uncertain.
