First World War Acoustic Mirror Saved

Fulwell Acoustic Mirror is a 4m high concave concrete dish, constructed on the coast at Fulwell, Sunderland. Completed in 1917, it was designed to act as an acoustic early warning system against air raids, after a bomb dropped by a Zeppelin over the Wheatsheaf area of Sunderland in April 1916 left 22 people dead and more than 100 injured.

After many years of neglect the acoustic mirror’s crumbling condition led to the structure being included on the Historic England (previously known as English Heritage) Heritage at Risk register. This triggered a partnership between Sunderland City Council, Historic England and the Heritage Lottery Fund programme – Limestone Landscapes, which has resulted in a glorious restoration, unveiled on 9 June 2015.
