According to historical authors, at the beginning of the 13th century there were around 80 fountains of this type in Fes.[1]:57 These wall fountains of Fes generally share similar characteristics and decoration. Their original construction was often an act of charity sponsored by patrons with means, which is sometimes recorded by a surviving inscription. They are often decorated with zellij tiling, carved stucco, and a canopy of carved wood or even of muqarnas.[67]
