Offerton, parch mark

Rectangular parch mark visible on Google Earth in an arable field north of Offerton village. It is approx 61m x 213m in size and takes the form of a rectangle with a square at the eastern end. There may be another square feature to the immediate north. Given the close proximity of Offerton medieval village and the river crossing or dam (possibly Roman or medieval at Hylton) this could be archaeological in origin. However it looks very angular in shape and may be related to agricultural activity. Local residents may undertake fieldwalking on the site.
