Droitwich, Worcestershire

Salt and vinegar?

English Buildings: all architectural life is here, from cathedrals to parish churches, even unto the Droitwich Spa Fish & Chip Bar. I took this picture because it seemed to me a very clear illustration of a problem that became pervasive in Droitwich, leading to a major change in the economy in the late-20th century. The problem is obvious enough: subsidence, which occurs when the ground under a building sinks, causing the foundations and also the above-ground structure to move, leading to cracks, sloping floors, wonky walls, all kinds of structural chaos. The cause is less obvious. Subsidence occurred here because of the extraction of brine from the large underground deposits beneath the town.

Beneath Droitwich are large deposits of rock salt. When surface water penetrates the ground it dissolves the salt, producing the liquid called brine. By pumping the brine to the surface and heating it, people produced salt in huge quantities, for Droitwich’s brine contains around ten times as much salt as sea water. So brine extraction became a major industry in Droitwich and nearby Stoke Prior (there are more salt deposits in Staffordshire, Lancashire, and, especially, Cheshire).

Salt-working in Droitwich grew to a large scale in the 17th to 18th centuries, and continued through the 19th. By the 1920s, large-scale working in Cheshire and elsewhere sent the Worcestershire industry in decline, continuing on a small scale. But by this time, the damage to buildings had already begun. The resulting damage was a further nail in the coffin of the salt works, and by the late-20th century, brine extraction in the town had ended. Some buildings still show obvious signs of the damage caused by subsidence but none, I think, quite so clearly and outwardly as this one. It’s drastic, but the building still seems to serve up England’s traditional fast food. Salt and vinegar anyone?
