“ This is one of the largest townships in the Cleveland ironstone district, and its industrial population is wholly employed in the quarries. The modern Skelton Castle incorporates part of the ancient stronghold of Robert de Brus who held it from William the Conqueror. A modern church replaces the ancient one, of which there are ruins, and a fine Norman font is preserved. The large ironstone quarries have not wholly destroyed the beauty of the district. The Cleveland hills rise sharply southward, to elevations sometimes exceeding 1000 ft., and are scored with deep and picturesque glens. ”
