This is pretty much the centre of the archaic, monolithic and largely closed institution that is the British state. Horse Guards Parade is virtually next door to 10 Downing Street, and Buckingham Palace is just a few hundred yards away. On this gravel the Queen Troops the Colour (whatever the hell that means) to celebrate her own “official birthday”. Until 1997 it was used as a car park, unbelievably, and the beach volleyball was played here in the 2012 Olympics.
