Changing the Guard – also known as Guard Mounting – is the iconic ceremony which is seen by millions of people each year at Buckingham Palace and Windsor Castle. Carried out by soldiers on active duty from the Foot Guards who have guarded the Sovereign and the Royal Palaces since 1660, the sight of their famous bearskin hats and red tunics is indelibly linked with Buckingham Palace and the British Monarchy
