We are planning a visit to Buckingham Palace, London. It is known that the Changing of the Guards take place at 11:30 am, lasting about 45 minutes.
So it seems we could watch this ceremony, and then visit the State Rooms at about 12:30.
But I'm confused of this: Do we need a ticket to watch the Guard Changing? Or we just wait outside the Palace to witness it?
My sincere thanks,
