Boldron is a small village of around 40 houses and a number of outlying farms in Teesdale, part of the North Pennine area of England. Boldron was in the North Riding of Yorkshire until 1974 and is currently in County Durham. The name Boldron means "bull clearing" in old Norse, with other evidence of a Viking presence in the area being the name Thorsgill Beck for a stream on the parish boundary.
Boldron lies less than half a mile from the road that leads to Stainmore Pass, an ancient route way across the North Pennines; the Romans and later the Normans built forts at Bowes (2 miles away from Boldron) to guard it. There is no mention of Boldron or Bowes in the Domesday Book, (possibly due to the harrying of the North in the decade previously) but they were part of the Earl of Richmond’s holdings in later Norman times. The surrounding fields show signs of medieval ridge and furrow ploughing and there is evidence of a barmkin (a medieval defensive enclosure) in one of the fields behind the village street. Although Boldron is many miles from the current border with Scotland, the area was raided by the Scots in the 11th and 14th centuries with Bowes Castle being damaged in both incidents. Boldron parish is first mentioned in the historical record in the 12th Century, in the settlement of a dispute between the Hospital of St Peter, York and Alan, Rector of Startforth, regarding payment of tithes. It is also mentioned in the 14th Century as part of the Manor of Bowes.
