[00:06.160]Buckingham Palace is the monarch's principal state residence. [00:12.682]And at its heart is a proclamation of royal authority. [00:24.287]If you had to pick just one room [00:26.599]which encapsulates what Buckingham Palace represents, [00:29.559]it's this one. [00:30.973]The Throne Room. [00:32.703]And you're in no doubt where the seat of power lies. [00:35.416]The two chairs on a raised dais, [00:37.362]one for Queen Elizabeth the Second, [00:38.978]one for her consort, Prince Philip. [00:41.284]And you might pick [00:42.731]that the Queen has sat on that seat many times during her reign [00:46.136]and received dozens of heads of state here. [00:49.549]But you'd be wrong. [00:50.513]This room is purely symbolic, [00:52.844]and she's only sat on that chair the once, [00:54.289]at her coronation in 1953.
