An English Masterpiece. After an immense process of careful restoration and conservation, the outstanding artistry of the Great East Window is revealed afresh through state-of-the art photography that captures the complete sequence of major panels, in corrected placements, for the very first time. At the size of a tennis court, it is the largest single expanse of medieval stained glass in Britain and one of the largest medieval windows ever made. This visual feast is brought to life by expert author Sarah Brown, who explores the history, artistry, meaning and restoration of the window, that has been described as England's Sistine Chapel.
