This is taken from the book: “The Story Of Cleveland” by “Minnie C. Horton” . p278
“The eastern end of the Eston Hills known as Court Green was, in the opinion of Mr. O. hill, a place of importance in the mid Bronze Age, for not only were there barrows, but a stone circle is reputed to have stood there.”
I dont know much about Mr O hill except that he was a historian and the information came from the local news paper the Evening Gazette in 1959.
