Knook Castle hill fort

Knook Castle is the site of an Iron Age univallate hillfort on Knook Down, near the village of Knook in Wiltshire, England, but within the civil parish of Upton Lovell. It has also been interpreted as a defensive cattle enclosure associated with nearby Romano-British settlements. It is roughly rectangular in plan with a single entrance on the south/southeast side, but with a later break in the wall on the western side.John Marius Wilson's Imperial Gazetteer of England and Wales described Knook Castle as follows:

Knook Castle is an ancient single ditched entrenchment, of about 2 acres; is supposed to have been originally a British village, and afterwards a Roman summer camp; and has yielded Roman coins. Traces of another ancient British village are to the N. "The site of these villages", says Sir R.
