Pre Radar Early Warning System
This year we spent Leigh’s birthday photographing Boulby Sound mirror.
Sound mirrors or whisper dishes were forerunners of radar and these ‘listening ears’ were intended to provide early warning of incoming attacks on coastal towns.
The grade II listed sound mirror at Boulby on the Yorkshire coast was built in 1916, during the First World War.
This sound mirror was used specifically to provide early warning of Zeppelin attacks on the Skinningrove mustard gas factory 5 km to the North West.
