1957
The Urban District Of Warminster Official Guide 1957/8 noted that:
Arn Hill . . . . The Marquess of Bath has presented the wooded hillside to the town as a recreation ground. The views from Arn Hill across the wooded valleys to the opposite slopes of the Plain on the one side and the Mendips on the other are amazingly fine, and the whole of this part of the downs is a treasure house for the botanist.
