High Quality Content by WIKIPEDIA articles! The Weaver Hall Museum and Workhouse, Northwich, Cheshire, records the social, cultural and industrial history of west Cheshire. It was formerly known as the Salt Museum, reflecting its earlier focus on the history of salt extraction, a local industry dating back to Roman times. The museum was renamed Weaver Hall Museum in 2010 as its remit now extends to cover the broader history of the area and also the history of the building itself as a former workhouse.
