Relics of attempts at building an early warning system in the days before radar was invented, sound mirrors still stand along the south and east coasts of England (there’s also one on Malta).
The three huge mirrors at Dungeness in Kent have become quite famous, but others are less well known, particularly the World War I mirrors built to watch for Zeppelins approaching the coast of Yorkshire and County Durham.
What were they? Did they work? Which ones have survived? How do I visit one for my photo shoot/music video/art project? Read on…
I occasionally add new bits of information about sound mirrors to the site; subscribe to the Sound Mirrors RSS feed for updates.
