There are 53 Grade I listed buildings in Sedgemoor, 14 of which are on Castle Street, Bridgwater. Sedgemoor is a local government district in the English county of Somerset. In the United Kingdom, the term listed building refers to a building or other structure officially designated as being of special architectural, historical or cultural significance; Grade I structures are those considered to be "buildings of exceptional interest". From 1723 to 1728, Castle Street was built on the site of the demolished Bridgwater Castle, as homes for the merchants trading in the town's port. Outside the town of Bridgwater, the largest concentration of Grade I listed buildings are in the village of Cannington, where the 12th-century Cannington Court and 14th-century St Mary's Church (pictured) were both associated with a Benedictine nunnery. Most of the Grade I listed buildings in Sedgemoor are Norman- or medieval-era churches, many of which are included in the Somerset towers, a collection of distinctive, mostly spireless Gothic church towers.
