Droitwich Spa (often abbreviated to Droitwich ) is an historic spa town in the Wychavon district in northern Worcestershire, England, on the River Salwarpe. It is located approximately south-west of Birmingham and north-east of Worcester.
The town was called Salinae in Roman times, then later called Wyche, derived from the Anglo-Saxon Hwicce kingdom, referred to as "Saltwich" according to Anglo-Saxon charters, with the Droit (meaning "right" in French) added when the town was given its charter on 1 August 1215 by King John. The "Spa" was added in the 19th century when John Corbett developed the town's spa facilities. The River Salwarpe running through Droitwich is likely derived from sal meaning "salt" and weorp which means "to throw up" - i.e. "the river which throws up salt" - which overflows from the salt brines.
The town is situated on massive deposits of salt, and salt has been extracted there since ancient times. The natural Droitwich brine contains of salt; ten times stronger than sea water and rivaled only by the Dead Sea.
History
During the Roman era the settlement was known as Salinae and was located at the crossroads of several Roman roads. Railway construction in 1847 revealed Roman mosaic pavements. In the ninth century Historia Brittonum, a text that discusses various landscape folklore across Britain, the hot spring of Droitwich Spa appears to be described in a passage that suggests that the spa was still built up at that time: "The third marvel is a hot pool, which is in the country of the Hwicce [near Worcester] and is surrounded by a wall made of bricks and stone. Men go into it to bathe at all times, and the temperature changes for each of them as they wish: if one man wants a cold bath, it will be cold, and if another wants a hot bath, it will be hot."
Droitwich remained a fairly small town until the 1960s, when the population was still barely 7,000, but since then it has grown considerably from overspill from Birmingham with many housing estates being developed in the 1970s and 1980s. In 2014, new housing consent was granted to large developments at Copcut (750 houses) and Yew Tree Hill (765 houses) with a number of other in-fill developments
In July 2007, Droitwich was hit heavily by the UK-wide flooding caused by some of the heaviest rainfall in many years. The flooding was pictured in UK-wide news, having flooded the majority of the heavily subsided high street. Many shops in the high street remained closed almost a year later. The flooding crossed from the stream and canal in Vines Park, crossed Roman Way, and spilled across to the High Street some 110 yards from the source stream.
Following specialist inspections at Droitwich Spa Brine Baths on 12 December 2008, the facility was closed to allow further building investigations to take place and to avoid any potential hazard to the public or staff.
Salt and brine
Rock salt and brine was extracted by the Romans and this continued through to the Middle Ages. A salt tax was levied by the king until it was abolished in 1825. A local family named Wintour owned up to 25 salt evaporating pans in the area by the 1600s.
Brine rose naturally to the surface at three sites along the River Salwarpe within Vines Park in the centre of Droitwich. Unusually the brine was fully saturated with sodium chloride, and was extremely valuable because it was economic to boil, and the yield of salt was high. Because of its value the brine was divided into shares, one share comprising which produced of salt annually in the set boiling period. When it rained, particularly in the winter when brine was not being boiled, the rain water which is less dense than saltwater, settled on top of the brine and was readily removed.
Originally brine for boiling was extracted with buckets lowered into the pits which were naturally replenished. Upwich, the deepest of the three pits at , supplied most of the brine, while the pit at Netherwich was only deep. The Middlewich pit, located between the two, was adversely affected by brine extraction at the other two pits and fell into disuse. Steynor in the 17th century discovered the pit and set up business for himself, but eventually due to the lack of brine he failed to compete with the town monopoly.
The underground brine reservoirs were only deep and in 1725 boreholes were sunk to the base of the pits, accessing brine in almost unlimited quantities and independent of the natural brine flow, and the monopoly ceased. Pumps were used to draw brine, and production increased. As a result, parts of the town succumbed to subsidence.
