The remains on the tell from the Crusader period include a small tower,[1] a pool and an aqueduct - the only remains from the Crusader castle of Turris Salinarum ('Saltworks Tower'), Burj al-Malih in Arabic.[citation needed] Researchers suppose that the site was utilised for salt production, giving its name to the Crusader castle. The site became abandoned again during the late Middle Ages.[citation needed]
