Boundary Wall Around Fort House with Attached Structures

The boundary wall around Fort House, with attached structures, is a Grade II* listed feature located in Seaton Sluice. Built around 1917, it incorporates earlier structures on the south side. The wall is primarily made of concrete, except for the south section, which consists of coursed rubble topped with slag coping. This rectangular enclosure is interrupted by extensions to Fort House, situated south of the center on the east side. The flat-topped concrete wall stands between 1.2 and 1.5 meters high and is supported by frequent internal buttresses that hold stubs of stanchions for barbed wire fencing. There are small gateways located on the north side and in the southern part of the east wall.

At the north-west corner, there is a projecting pillbox with a canted external angle, featuring steel embrasures with cover plates. Near the south end of the west side, an attached blockhouse has a similar embrasure in its external wall, along with two boarded doors on the north and two 4-pane sash windows on the south, topped by a flat concrete roof. The south wall includes an entrance gate near the west end, flanked by concrete piers with pyramidal caps that are painted white. Additionally, the east wall incorporates one end of a building that is likely from the 18th century.

This structure is a rare survival of a World War I fort, and the north-west pillbox is noted to be unique in the North of England.
