BRIDGNORTH, municipal borough, Shropshire, England, situated on a high, red sandstone rock bounded on the east by the River Severn. Pop. (1931) 5,151. The approach from all sides involves steep ascents or descents. The early history of Bridg north is connected with Aethelfleda, lady of the Mercians, who raised a mound there in 912 as part of her offensive policy against the Danes. William I. granted the manor to Earl Roger of Shrewsbury, whose son built a castle on the sandstone rock in 110 1. The castle was finally destroyed by the parliamentarian forces in the Civil War, with the exception of part of the keep. Early charters were confirmed by several later kings, and the town was incorporated in 1546.
The borough returned two members to parliament from 1295 to 1867. It now forms part of the Ludlow parliamentary division of Shropshire. It is governed by a mayor, four aldermen and 12 councillors. Area 3,018 acres.
