Dar al-Magana is a historic 14th-century building housing a unique water clock. Built by Sultan Abu Inan in 1357, it operated using a complex system of weights and floats. It consists of 13 windows, each opening hourly to drop a weight into a brass bowl. The clock has not worked for centuries; bowls were removed for restoration. Legend says philosopher Maimonides lived here, adding mystique to the site.
