Dar al-Magana (Arabic for "clockhouse") is a house in Fes, Morocco, built by the Marinid Sultan Abu Inan Faris which holds a weight-powered water clock. The muwaqqit[1] Abou al-Hassan Ibn Ali Ahmed Tlemsani[2] was responsible for building the clock, which was finished on 6 May 1357. The Dar al-Magana is opposite the Bou Inania Madrasa and connected to this school.
