River Dun (River Test)
The River Dun is a river that flows through the counties of Wiltshire and Hampshire in England. The River Dun rises in Wiltshire to the south-east of Salisbury near West Grimstead, and flows east into Hampshire before joining the River Test at Kimbridge, ultimately draining to the Solent.
The valley of the Dun is followed by the Southampton to Salisbury railway. It was also used as the route of the Salisbury and Southampton Canal between Kimbridge and East Grimstead. This is marked as the Old Canal on modern maps.
