The World War I early warning acoustic mirror 335m north east of Kilnsea Grange is one of only four known surviving examples in the north east of England, and the only known example in the country that still retains its sounding column. The device survives well and makes a significant contribution to the study of early 20th century defences in England. At their most sophisticated, the devices could identify the sounds of surface vessels or aircraft up to 25 miles (c40km) away.
