Durham University Archaeologists Uncover 11th-Century Anglo-Norman Crypt Below Durham Castle

Archaeologists and historians from Durham University have made an extraordinary discovery beneath the courtyard of historic Durham Castle, home to University College since 1837.

During structural conservation works, researchers uncovered a sealed subterranean chamber dating back to the late 11th century. Preliminary analysis indicates the vault served as an early Norman chapter room and treasury during the bishopric of William of St. Calais.

"Durham Castle and Cathedral represent one of Europe's most significant Romanesque complexes," said Professor Richard Hall, Lead Archaeologist. "Finding an unrecorded early Norman chamber provides unprecedented insights into the administrative and spiritual life of medieval Northumbria."

The excavation site will be 3D laser-scanned for open digital research and virtual public exhibition starting this winter.
