The Queen's Guard is the name given to the contingent of infantry responsible for guarding Buckingham Palace.
They provide sentries during the day and night, and during the later hours, they patrol the grounds of the Palace. Until 1959, the sentries at Buckingham Palace were stationed outside the fence. This stopped following an incident involving a female tourist and a Coldstream Guardsman – due to the continued pestering by tourists and sightseers, the guardsman kicked the tourist on the ankle as he marched. The tourist made a complaint to the police and the sentry was confined to barracks for ten days. Not long after, the sentries were moved inside the fence.
