Ashley's Copse is the site of an Iron Age hillfort near to Salisbury. The Hampshire Wiltshire border runs right through the middle of this site. The site is half wooded, and here can be found the best preserved earthworks, but there is also visible evidence of some of the earthworks on the eastern spur of the hill. To the Southeast of the fort lies a steep valley, forming a natural defense. The flanks to the North and East are also tightly contoured. The ground on the other aspects slopes less steeply.
