The Gatehouse at Bonds Mill

The Gatehouse at Bonds Mill at Stonehouse, Gloucestershire, England, was constructed during World War II as a defensive pillbox as part of the Stop Line Green.

It has an octagonal floorplan based on the Type 24 pillbox, the ground floor being constructed of reinforced concrete and the upper storey is red brick.

It is situated on the north side of the canal, across from the former Bond's Mill, which was being used during the war by Sperry as a dispersal factory to manufacture gyroscopic compasses.

The historic swing bridge had survived the closure of the navigation in 1954, but had been widened and was no longer operable - it was in a very poor structural condition by the early 1990s.

[3] The composite lift bridge has not been in regular operation while awaiting restoration of the rest of the canal, and has now deteriorated mechanically and structurally to the point where replacement is likely to be required[6][3] as part of Phase 1B "The Missing Mile" reconnection to the national waterway network by 2025, likely with a conventional steel/counterweight design similar to that fitted at Lodgemore.
