Lying just west of Flaxley in Welshbury Woods, is Welshbury Hill. This Iron Age hill fort has impressive triple defensive rampart and ditches on its south and west sides with a single bank and ditch on the north and east and an entrance. It lies on Forestry Commission land, and is accessible to the public. It has never been excavated but in recent years it has been damaged by forestry operations and to minimise this the Forestry Commission has reverted to using horses on the site. Two interesting archaeological finds are associated with Welshbury, firstly a Celtic electrum coin which was found in fields nearby and depicts a stag or horse and secondly, an iron spearhead of Roman military style, which was found inside the ramparts after ground disturbance due to logging. Below the north ramparts of Welshbury is the enigmatic St Anthony's Well, an ancient spring whose name dates from the medieval period. However prehistoric flint implements have been found in the springs vicinity as well as Iron Age and Roman artefacts and it seems likely that the well was a ritual site for a long period of time. Saint Anthony's Well water is always extremely cold and for generations local people have bathed in it for the treatment of rheumatism and arthritis.
