Rosedale Rd goes from Bell Road near the Chester Co line - all the way to Noble Rd in Bartville. If you follow the road from the Chester Co line, Rosedale Schoolhouse is between Street Rd and Sproul Rd on the RIGHT-hand side. If you are coming from Bartville it is on the LEFT.
It is now a white stucco one-story house with a cement plaque over the door.
