Battery Observation Post

The Battery Observation Post is a two-storey building constructed in 1940 from reinforced concrete. It features steps leading down to a first-floor balcony, which has a cantilevered roof that provides a view out to sea. The entrance to the ground floor is located directly below the balcony, with a wide opening. The upper storey housed high precision range finders and served as the communication center for the searchlight positions and guns. A Bar and Stroud range finder was located in the lower part of the building. This post was the operational focal point of the Emergency Coastal Defence Battery, one of many built in 1940 to enhance protection for harbour installations. The Battery Observation Post supported gun emplacements located approximately 100 meters to the east along the upper shoreline, as well as a series of mobile guns stationed on the marshes. This structure is an integral part of one of the most complete 20th century coastal batteries still in existence, representing the rapid development of Britain's coastal defenses during the early stages of the Second World War. It is also part of a nationally significant grouping of coastal defenses on the Suffolk coast that dates back to the Napoleonic period.
