Monument record 2513/1 - Alliance Salt Works

In 1856 John Thompson Sr and John Thompson Jr obtained a 50 year lease for the Outlet Field, where they built the predecessor to the Lion Salt Works (CHER 2513/0), the Alliance Salt Works (this monument). Before this, rock salt was first exploited in Marston in 1781, when John Gilbert the elder, engineer and factor to the Duke of Bridgewater, bought the Symme Fields for £2000. He developed the Marston Mine, to the west of what would become the Alliance Salt Works, by sinking a c 100m deep shaft and installing an engine to wind rock salt and pump brine (18).

The Alliance Works were served by the canal arm of the Trent and Mersey Canal, and later by the Marston Branch of the Cheshire Midland Railway, and John Gilbert had previously been involved in the canal's construction. In 1888, The Thompson family sold the Works to the Salt Union, a group of businesses that intended to regulate potential fluctuation in salt prices.

Following a difference of opinion between the Salt Union and the Thompson family, John Thompson Jr and his son Henry Ingram Thompson built a new Works in 1894, next to the first, in the coal yard of the Red Lion Hotel, leading to the new facility being called the ‘Lion Salt Works.

The Alliance Salt Works continued to operate even after the Lion Salt Works was established, and in 1898 the shaft was inspected by Thomas Ward, following complaints from the Salt Union about John Thompson’s blasting within the Lion Salt Works shaft. The Alliance shaft was found to be in poor condition, and in the same year, it collapsed, which eventually lead to the abandonment of the Alliance Works at some time around 1910. The site of the Alliance Works passed from the Salt Union into the ownership of Imperial Chemical Industries, who retained the salt rights (18).

The 2013 excavation also revealed the well-preserved remains of nineteenth and twentieth century structures. Six distinct phases of activity were identified during the excavation: the initial establishment of the Alliance Works in 1856, the construction of the Alliance Works pan smithy and associated boiler/ engine house in the early 1860s, the development of the Lion Salt Works in 1894 and specifically, the construction of the fisheries pans and associated chimney and flues, the laying of cast-iron pipes in 1938 to replace the brine shaft pumping mechanism beneath the brine tank, the construction of Stove House Five in 1965, and activity on site following the closure of the Works in 1986.
