Until around 1940 Winspit was used as a stone quarry, producing stone for major buildings in London. Then during World War II it was used as a site for naval and air defences. After the war the caves were opened to the public. They were used as a location for the planet Mecron II in the Blake's 7 episode "Games", and in Doctor Who they were used in the story "The Underwater Menace" and then as the planet Skaro in the serial "Destiny of the Daleks". The quarry is now a lesser-known tourist attraction. Recently many of Winspit's caves have been closed off for public safety and bat conservation.
