Kilnsea Sound Mirror
Kilnsea Sound Mirror is located near Kilnsea, Yorkshire.It is the only listed ‘building’ in Kilnsea.
In World War I the Germans used Zeppelins to make bombing raids on eastern England. In order to have some warning of their approach, acoustic sound mirrors made of concrete were erected at various points along the coast. The Kilnsea sound mirror was probably built in 1916/17. It is in the shape of a half-hexagon, with an inner concave circular disc to amplify sound. It is 16 feet high and 17 feet wide. In front of the concrete disc is a plinth, with a pipe on which would have been mounted a trumpet-shaped 'collector head' which was a basic microphone.
