Sound Mirrors
"Sound Mirrors" also known as "Acoustic Mirrors" at Denge near Greatstone and Dungeness. This is a former RAF site where in the late twenties and early thirties, experimental buildings were built to provide early warning of aircraft reaching Britain. The "ears" were designed to capture sound.
You can only get close to the Sound Mirrors on a couple of days a year. When we visited, a Sony crew were filming some kind of promotional video.

Acoustic mirror at Denge
Prior to World War II and the invention of radar, acoustic mirrors were built as early warning devices around the coasts of Great Britain, with the aim of detecting airborne invasions. The most famous of these devices still stand at Denge on the Dungeness peninsula and at Hythe in Kent. Other examples exist in other parts of Britain (including Sunderland, Redcar, Boulby, Kilnsea) and Selsey Bill, and Bahar ic-Caghaq in Malta. The Maltese sound mirror is known locally as "the ear" (il-Widna) and appears to be the only sound mirror built outside Great Britain.
