Spring Cleaning Takes Place At English Heritage Properties Around The UK

YORK, ENGLAND - FEBRUARY 12: An exterior view of the foreboding York Cold War Bunker on February 12, 2016 in York, United Kingdom. York Cold War Bunker was in active service from the 1960's - 1990's and was designed as a nerve-centre to monitor fall-out in the event of a nuclear attack. The bomb-proof semi-subterranean nerve centre is now run by English Heritage. English Heritage staff across the country have been spring cleaning their historic sites, from castles to houses and even a cold war bunker, to prepare for their seven-day opening in time for the Easter Holiday.
