Nancuke Airfield
RAF Portreath was opened in March 1941 as a base for bombing raids against the occupied French Channel ports and fighter escorts for shipping convoys. Later in the war it became the main "jumping off" point for equipment headed south. The airfield was closed in 1946 and taken over by the Ministry of Supply where it was used as a secret base for chemical weapons manufacture. Long after its closure in the late 1970s, it emerged that former workers there had died of exposure to the nerve gas, sarin. As a precautionary measure, a large cleanup operation was mounted in 2000, though no residues of toxic materials were found to be remaining.
