Gloucester Cathedral, East Window
Publisher: Francis Frith & Co, Reigate
At the time of its installation in the 1350s, the Great East Window was the largest window in the world. Today, it is still one of the greatest landmarks of English, and indeed European, medieval stained glass. It measures 22 metres in height and 12 metres in width. In fact, it is as big as a tennis court! The window was created as part of the reconstruction of the Quire following the burial of King Edward II and fills the entire wall behind the high altar.
