The Pool of the Arches in Ramla has been studied architecturally and historically, but never tested archaeologically. Large-scale conservation works at the site offered a rare opportunity for an archaeological examination. Two areas were opened with the aim of revealing the water inlet into the pool and to resolve the reason for the construction of the pool at this location. Based on pottery finds, it seems that the pool ceased to be used during the Tulunid regime, in the late ninth or the beginning of the tenth century CE. This dating matches the date in which the Umayyad aqueduct ceased to function, and thus, it seems that the aqueduct conveyed water to the pool from the springs around Tel Gezer.
