The Abu Jaber House is Salt's most impressive building and the anchor of any tour through the old town. Built in the 1890s for a wealthy merchant family, it is a three-storey limestone mansion with the characteristic arched windows, ornamental ironwork, and interior courtyards typical of the Ottoman Levantine style. The ground floor now houses the Salt Archaeological Museum.
The museum collection covers the layers of habitation in the Balqa region from the Bronze Age through the Islamic period. Among the exhibits are pottery, coins, and architectural fragments recovered from sites in the surrounding hills. The Abu Jaber family were significant figures in Salt's commercial life for generations, and their story is bound up with the broader history of trade between the Jordanian highlands and the Mediterranean world.
