Hartlepool sound mirror
There is a reference to a sound mirror in Hartlepool on the Hartlepool Today website. Hartlepool resident JW Perrin mentions a sound mirror or “Zeppelin Listening Post” in the Clavering area, and asks for more details of the mirror.
Perrin says the mirror was constucted in or about 1916, which would make it a contempory of the Redcar structure. A sketch accompanying the text shows a mirror with the same design as the ones at Boulby and Redcar. It was “demolished possibly in the early Sixties when the new housing development commenced”.
Perrin says the Hartlepool mirror “played an important part in the Air Defence of the North-East Region in World War One, including the shooting-down of the Zeppelin over Teesmouth on November 27, 1916″.
Unknown. This newspaper letter is the only reference to this mirror which I’ve seen – more information would be very welcome.
