Marrakech to Fes: home to one of the oldest water clocks in the world

Water clocks are the oldest form of time keeping in the world. Fez is home to one of these old devices well preserved in Dar al-Magana, meaning “clock-house”. Built by the “muwaqqit” (time keeper) Abou al-Hassan Ibn Ali Ahmed Tlemsani, the clock was finished on May 6, 1357, and kept inside Dar al-Magana, a house built by the Marinid Sultan Abu Inan Faris.
