Northwich Salt Museum Railway wagon with a dramatic sky. The area around Northwich has been exploited for its salt pans since Roman times, when the settlement was known as Condate. The town has been severely affected by salt mining with subsidence historically being a large problem. However, recent investment in mine stabilisation is set to change the town with the 'Northwich Vision' being a plan for future development work. During the 19th century it became uneconomical to mine for the salt. Instead hot water was pumped through the mines, which dissolved the salt. The resultant brine was pumped out and the salt extracted from the brine. This technique weakened the mines and led to land subsidence as they collapsed. Subsidence affected the town and the surrounding landscape. For example collapses in 1880 formed Witton Flash as the River Weaver flowed into a huge hole caused by subsidence. Subsidence also allegedly accounts for many old timber-framed houses in the town centre, which were better able to withstand the movement of the ground. Some houses were built on a base of steel girders which could be jacked up to level the house with each change in the underlying ground. The town's historical link with the salt industry is celebrated in its Museum which is today located in the town's old workhouse.
