St Mary's Priory, Binham, or Binham Priory, is a ruined Benedictine priory located in the village of Binham in the English county of Norfolk. Today the nave of the much larger priory church has become the Church of St. Mary and the Holy Cross and is still used as a place of worship. The remains of the priory are in the care of English Heritage. A Ley tunnel is said to run from the buildings to an unknown destination and many years ago a fiddler decided to explore these passages; he could be heard for some distance before suddenly ceasing. The fiddler was never seen again.
