From 27 August this year until August 2010, visitors will be able to view previously unseen documents, letters, personal stories and artefacts revealing what life was like in the central shelter for government and military strategists during the Second World War.
To coincide with the new exhibition, titled The Undercover: Life in Churchill's Bunker, organisers have launched a daily delegate package that includes main meeting room hire, breakfast pastries, mid-morning refreshments, lunch and afternoon tea from £69 per person.
