Bridgwater Castle
Bridgwater Castle was a medieval stone castle in Bridgwater, Somerset, built in the early 13th century and sited on the town's only raised ground. It was surrounded by a wide tidal moat and included a watergate giving access to the quay; much of the complex was demolished from the 17th century onward and built over in later redevelopment. Sections of curtain wall, a watergate and an undercroft survive today.

As it stood in 1300
What Bridgwater Castle looked like in its prime.
A large enclosed castle of Old Red Sandstone occupying raised ground and covering roughly 8–9 acres, defined by continuous curtain walls, multiple projecting towers and a prominent keep at the south‑east corner. A broad tidal moat rings the site and a watergate provides direct access to the quay; the principal entrance consists of paired gate openings with drawbridge approach and an outer barbican. Rooflines would include crenellated wall-tops and clustered masonry towers, with service buildings lining an inner bailey.
Its story
The story of Bridgwater Castle.
The lordship of the Manor of Bridgwater was granted to William Brewer by King John in 1201, and the stone castle rose around 1220 on the town's only raised ground, ringed by a wide tidal moat with a watergate opening onto the quay. When Brewer's son, also William, died in 1232, the castle passed to the king the following year and was used as a store and prison.
In 1248 ownership passed to Maud de Braose, wife of Roger Mortimer, 1st Baron Mortimer, and the castle was drawn into the Second Barons' War. In the Despenser War of 1321 Edward II moved against the Mortimers, and the crown held Bridgwater until 1326 to deny Roger Mortimer, 1st Earl of March, a base. Once Mortimer and Queen Isabella had seized the throne the castle was returned to the family, but its upkeep was neglected and part of the moat filled in.
Parts were demolished in the first half of the 17th century and a new house built; the surviving walls played minor roles in the Civil War and the Monmouth Rebellion. In 1721 the remains were sold to James Brydges, 1st Duke of Chandos, who developed an industrial centre in the town and demolished the last of the buildings — the redevelopment that gave Castle Street its name. The watergate, an undercroft and sections of curtain wall survive.
