The tour -
link to virtual tour - takes in the main rooms of the house.
Virtual visitors will find some interesting titbits about the history of the house, which was presented by George II to Sir Robert Walpole, the first prime minister. For example, No 10's bricks are not naturally black, but yellow. The discoloration, due to pollution, became such a feature of the house that the bricks were painted black rather than cleaned during renovation work in the 1960s.
