The Sounds Mirrors of Lade Pit are the result of a programme to develop an aircraft early warning system before the advent of radar. I first heard about them over ten years ago when I read an article in the Sunday Telegraph magazine on Dungeness. I was intrigued and wanted to go and see them but never got around to doing anything about it until last year. The sound mirrors are on private land and not normally accessible to the public. On 17th August 2008 I attended a walk led by Dr Scarth, apparently the world’s expert on sound mirrors, who told the fascinating story behind them.
