The changing of the guard at Buckingham Palace—the official London residence of the British royal family—presents a colorful spectacle. Accompanied by a band, the new guard marches from a nearby barracks to the palace, where the troops form up facing the old guard. As the changeover takes place, the officers of the old and new contingents advance and touch left hands to symbolize the transfer of keys.
