670 Rebuilding work The stone church has fallen into disrepair since its construction when Saint Wilfred ascends to See of York in 670. He directs the repair and construction of both the main church and the attached school and library. Over the next century these become amongst the most substantial such institutions in Europe.

9th July 1984 Fire The south transept's roof was set alight by a lightning strike during the early morning hours. To save the rest of the building a decision was made by firefighters to collapse the roof deliberately by pouring many thousands of gallons of water onto it. This, while destroying the ancient timbers of the transept prevented the fire from spreading to other parts of the building.
