 A parapet protected the guns, a new entrance was cut into the main tower and other adjustments made.The antiquary William Borlase visited the castle in 1752, noting that the gun platform was armed with 9-pounder (4 kg) cannons and the tower roof with 4-pounder (1.8 kg) guns.The site was now unmanned, however, and had fallen into decay since the construction work by Tovey.
