As free experiences in London go, you can't get much more famous than the Changing of the Guard at Buckingham Palace.

Every morning at 11am, and running for 45 minutes to around 11:45 you can watch a historic routine, accompanied by rousing music - in front of the home of the King of England.

Head there for 11am to see the action, and for the finer details as to who is accompanying the Guards as they move about, you can visit Changing Guard.
