Bou Inania Medersa

Built between 1350 and 1357 by the Marinid sultan Abu Inan, this theological college in Fes is considered the masterpiece of Moroccan decorative art. Every surface is worked: zellige tilework below eye level, carved stucco above, and cedarwood muqarnas crowning the interior. It is the only medersa in Morocco with its own minaret — making it both a school and a functioning mosque. The water clock on the exterior wall, a bronze mechanism with 13 windows, is one of the few medieval clocks surviving anywhere. The marble courtyard channels water through carved channels to each corner.
