Kilnsea Sound Mirror
This concrete structure dates from WWI and is at Kilnsea in Yorkshire.
Before the advent of radar in WWII, sound mirrors were devices positioned around the south and east coasts to try to detect incoming German bombers and airships.
The metal post in front of the mirror had a microphone attached to gather the reflected sounds.
