In architecture, a Nubian vault is a type of curved surface forming a vaulted structure. The mudbrick structure was revived by Egyptian architect Hassan Fathy after re-discovering the technique in the Nubian village of Abu al-Riche. The technology is advocated by environmentalists as environmentally friendly and sustainable since it makes use of pure earth without the need of timber. The technology is of Nubian origin.
