Sadd el-Kafara ("Dam of the Infidels") was a masonry embankment dam on Wadi al-Garawi 10 km southeast of Helwan in Helwan Governorate, Egypt. The dam was built in the first half of the third millennium BC by the ancient Egyptians for flood control and is the oldest dam of such size in the world. Never completed, the dam was under construction for 10–12 years before being destroyed by a flood. It was rediscovered by Georg Schweinfurth in 1885.
