1 LAWN. This is a lawn of bright green grass uniformly cut to a height of three inches. The doors to the east lead to Room 45 in the Ground Floor of the Inner Ward. The lawn is enclosed by sixteen foot tall walls, made of the same gray dressed stone as the Castle. It is possible to climb the wall, and a person could then walk along the top into the hedge maze or even to the towers at Areas 10 and 14.
