Salt is an ancient agricultural town and administrative centre in west-central Jordan. It is on the old main highway leading from Amman to Jerusalem. Situated in the Balqa highland, about 790–1100 metres above sea level, the town is built in the crook of three hills, close to the Jordan River valley. One of the three hills (Jebal Al Qal'a) is the site of a 13th century ruined fortress. It is the capital of the Balqa Governorate.
The Greater Salt Municipality has about 97,000 inhabitants (2006). 70% are Muslim and 30% Christians
