This Ceremony is held on the Sovereign's official birthday in June. This is the most colourful of all London's annual events, a pageantry of rare splendour with the Queen riding side-saddled on a highly trained horse. On Horse Guards' Parade in Whitehall the Queen inspects the Brigade of Guards, dressed in ceremonial uniforms. Then comes the Trooping ceremony, followed by the March past of the Guards to the music of the bands. Specially noted should be the precision drill of the regiments.
