The Chapel of St George at Windsor is one of the acknowledged masterpieces of late Medieval European architecture. It was begun by Edward IV in 1475 immediately to the west of the college's original chapel. This earlier building, of which little now remains, stood on the site of the present Albert Memorial Chapel.

Edward IV's new church was designed by the master mason Henry Janyns and was conceived on the grandest scale. The architectural ambition of the chapel reflects both its location within England's greatest royal castle and its role as the church of the Order of the Garter, one of the most prestigious chivalric orders of medieval Europe. Edward IV made his own funeral monument an integral part of the chapel, beginning a tradition of royal burial here that has continued through the centuries.

Preserved within the chapel is an exceptional collection of church furnishings, both medieval and modern. In a very real sense it remains the personal chapel of the sovereign as well as the focus of the college of St George and the Order of the Garter.
