Castle Ditches is the site of an Iron Age trivallate hillfort in the south-east of Tisbury parish in Wiltshire, England.
It is probable that its ancient name was Spelsbury; it was referred to as Willburge in Tisbury's charter of 984 A.D.[1] Its shape is roughly triangular, and follows the contours of the small hill upon which it sits. The earthworks comprise a triple row of ramparts and ditches, now covered on three sides by woodland. There is a large entrance towards the south-east, where there is the shallowest incline of the hill; but there is also a narrow slit on the opposite side. The area within the site encompasses nearly 24acres, and the greatest height of the ramparts is about 40feet.[2] [3] Castle Ditches was recorded as a Scheduled Monument in 1932.
The site is at, about NaNmiles south-east of Tisbury village. The hill has a summit of 193m AOD and overlooks the valley of the River Nadder to the north. Public footpaths surround the site, but the land is privately owned.
