You know Queen Mary, never ceases to impress me. I was reading about the Palace of Whitehall: An undercroft from Wolsey's Great Chamber, now known as Henry VIII's Wine Cellar, a fine example of a Tudor brick-vaulted roof, was in the way of plans for the new building of the Ministry of Defence. Following a request from Queen Mary and a promise in Parliament, provision was made for the preservation of the cellar. It was encased in steel and concrete and relocated in 1949. This major operation was carried out without damage to the structure and it now rests safe within the basement of the MOD.
Such a love of history and an eye to preservation for future generations!!
