Description:On the morning of November 27, 1944, a huge explosion took place after the accidental ignition of 3,500 tons of explosives stored by the RAF in a disused gypsum mine.
Upper Castle Hayes Farm was completely obliterated, and 70 people were killed. The crater remains, 90 feet deep and a quarter of a mile across.
The Cock Inn in Hanbury, half a mile away from the blast, was severely damaged, and was later completely rebuilt.
