A water tank of considerable proportions consisting of a longitudinal nave made up of slabs and covered with a barrel vault of the same material, the vault being interrupted by the housing of a series of skylights that have a truncated pyramid appearance. The existence of a nearby ditch, the missing steps that acted as separation and access to areas and the skylights of the vault all contribute to the hypothesis of the tank’s possible use as a Muslim public bath. It conserves the falsework through which the water entered, directly from Sierra Nevada. It has recently been restored and converted by the Town Hall into a room for various cultural uses. Located on Calle Castillo.
