Bridgnorth is a town and civil parish in Shropshire, England. The River Severn splits it into High Town and Low Town, the upper town on the right bank and the lower on the left bank of the River Severn. The population at the 2011 Census was 12,079.
Bridgnorth is named after a bridge over the River Severn, which was built further north than an earlier bridge at Quatford. The earliest historical reference to the town is in 895, when it is recorded that the Danes created a camp at Cwatbridge; subsequently in 912, Æthelfleda constructed a mound on the west bank of the River Severn, or possibly on the site of Bridgnorth Castle, as part of an offensive against the Danes. Earliest names for Bridgnorth include Brigge, Brug and Bruges, all referring to its position on the Severn.
After the Norman conquest, William I granted the manor of Bridgnorth to Roger de Montgomerie. The town itself was not created until 1101, when Robert of Bellême, 3rd Earl of Shrewsbury, the son of Roger de Montgomerie, moved from Quatford, constructing a castle and a church on the site of the modern-day town. The town became a royal borough on Robert Bellême's attainder in 1102. The castle's purpose was to defend against attacks from Wales. The town was attacked and burnt by Roger Mortimer, 1st Earl of March during the Despenser War in 1322.
Bridgnorth's town walls were initially constructed in timber between 1216 and 1223; murage grants allowed them to be upgraded to stone between the 13th and 15th centuries. By the 16th century, the antiquarian John Leland reported them in ruins and of the five gates, only one survives today.
It is probable that Henry I granted the burgesses certain privileges, for Henry II confirmed to them all the franchises and customs which they had had in the time of Henry I. King John in 1215 granted them freedom from toll throughout England except the city of London, and in 1227 Henry III conferred several new rights and liberties, among which were a gild merchant with a hanse.
