Britain's Queen Elizabeth II leaves after The Order of the Garter Service, at St. George's Chapel in Windsor Castle, Windsor, southern England on June 14, 2010. The Order of the Garter is the most senior and the oldest British Order of Chivalry and was founded by Edward III in 1348. The patron saint of the Order is St George (patron saint of soldiers and also of England) and the spiritual home of the Order is St George's Chapel, Windsor. Every knight is required to display a banner of his arms in the Chapel, together with a helmet, crest and sword and an enamelled stallplate. These 'achievements' are taken down on the knight's death and the insignia are returned to the Sovereign. The stallplates remain as a memorial and these now form one of the finest collections of heraldry in the world. AFP PHOTO / Alastair Grant/ POOL
