MoD CORSHAM: Slope Shaft (Emergency Exit) A is a Cold War defensive structure located at the Ministry of Defence establishment near Corsham in Wiltshire. The site dates from the early Cold War period, when the United Kingdom constructed a network of underground facilities to serve as protected command centres and shelters in the event of nuclear conflict. The slope shaft functioned as an emergency exit route from the subterranean complex, engineered to provide rapid evacuation pathways for personnel in crisis situations. This installation forms part of the broader strategic infrastructure developed during the nuclear deterrence era of the mid-twentieth century.
