Archaelogical evaluation outside the castle but within the scheduled grounds. Late post-medieval pottery (including one Border Ware sherd and several local, glazed brown wares of mid-C18th date), roof tile, bricks and slag. Interpreted as former ploughsoil from reworked natural. Slag may suggest post-medieval iron-working near the castle, or it may derive from attempts to 'sweeten' the heavy clay soils, a practice common from elsewhere. (1)
