A watching brief by D W Williams of work to this property, which cuts into the slope below the castle. Subsidence resulted in the destruction of a 19th century brick baking oven and a stone and brick revetment, before recording could take place, as well as the rear wall of this 16th-17th century building. Subsequent observation revealed a buried soil layer, which contained early Mesolithic flint blades and 13th century pottery, that had been disturbed by excavation, presumably for sand, at some point in the 13th century. This excavation had subsequently been infilled, firstly by the deposit of 13th century rubbish and secondly by a considerable depth of sand & sandstone, which presumably relates to the construction of earthworks at the castle.
