To resist any successful landing of troops on the beaches, reinforced, toughened concrete structures were built along cliff-tops and along many roads inland where they would be able to defend against the movement of any invading force. The pillbox was a low concrete structure with embrasures to allow weapons to fire out in various directions. For the sake of speed of completion the structures were designed and built to standard patterns that could be erected quickly by unskilled or semi-skilled workers. There would usually be an L-shaped blast wall at the entrance to protect the occupants from any nearby blast.
An extensive battery and barracks once occupied the cliff-top at Kilnsea and Easington. This gun mounting was once a part of the battery and has now collapsed onto the beach. Most of the battery is now either fallen onto the beach as the cliff has been washed away or has been removed for safety reasons.
Situated in a lovely hay-meadow on the river bank, these bunkers once housed a generator. Most likely this would have provided power for the searchlight and anti-aircraft batteries. It may also have provided the power for the decoys which were located on the river bank not far away. These decoys were accurate, small scale representations of the docks at the nearby city of Hull and were intended to fool German bombers into dropping their bombs into the river.
