In the context of Five Sisters window, explain the World War I of the History.
In 1916, during a German zeppelin raid, a bomb fell near the Minster. It caused no damage but prompted wholesale removal of the Minster's windows as a precaution. They were stored in the cellars of various country houses near York. During their removal, it was discovered that tiny holes had developed in the glass of the Five Sisters, which, as they grew, were causing the glass to "scale off" until only a thin shell of colour remained.  This meant that the windows were in urgent need of full restoration.
The lead holding the glass in place was also in poor condition and needed urgent repair. The owner of ruined 13th century Rievaulx Abbey in the North Riding of Yorkshire donated lead that had been stripped from the abbey's windows and stored sometime after the dissolution of the monasteries, bearing the stamp of Henry VIII.
