History & significance

Constructed during the First World War, this concrete structure represents one of several acoustic mirrors built along the English coast to detect enemy aircraft and ships before the development of radar technology. The mirror functioned by focusing and amplifying sound waves, allowing observers positioned at its focal point to detect approaching vessels or aircraft at considerable distance. Such installations formed part of the coastal defence infrastructure deployed during the war and the interwar period.
