Finds from these excavations included part of a leather book cover, a small die, a silver coin from the reign of Edward II and a large array of spent stone catapult balls from the English siege of 1277. In the course of the excavations, more than of debris and infill was removed to reach the castle's features. These included a small stone lined hall, English repairs to Welsh masonry (shown by different types of mortar), a suspected wheat-drying oven and a cistern/cellar well (with indication it might be deeper).
