It is believed that the shelters, that stand around 10 metres high, were built with a reinforced concrete ceiling about two metres thick, below a steel plate, around three metres of sand, a further reinforced concrete slab, all covered with tonnes of soil. Each shelter had six bombproof steel doors, three at each end.
RAF Greenham Common was abandoned many years ago and the site is now part business
park with the rest being returned to common land. The runway has been
removed and the last part of the hardstanding area for aircraft was
being dug out whilst we were there. Many new buildings have been built
to provide accommodation for a variety of businesses but a large number
of the original structures remain.
Site of major Cold War protests.
