Details of MOD land holdings with asset valuation over £1 million can be found in Chapter seven of the National Asset Register, last published by HM Treasury in 2007: http://www.official-documents.gov.uk/document/cm70/7022/7022.pdf

The National Asset Register is on a historic replacement cost basis, not market value. We do not routinely assess the current market value of all our estate because the estimated receipts will depend on market conditions and other factors.
