In 1714 the grammar school was rebuilt on its original site after many years of dilapidation. The governors obtained letters patent from George IV to exchange the land in Durham for land closer to the school in 1823. The Durham land was exchanged for Higher Knowles, Lower Knowles and Grut Farms in Rivington, and a house known as Jolly's in Heath Charnock which brought in annual rents. Higher Knowle farm is still active, Lower Knowle is a ruin, both located on the slope of Rivington Pike, Grut farm was once located opposite the entrance of the current Rivington and Blackrod High School driveway.
