Richard rebuilt the walls and the gatehouses at Launceston, building a high tower to increase the height of the keep, probably to allow guests to enjoy the view of his deer park. The bailey was cleared of its older buildings and a new great hall was constructed in the south-west corner. The castle's inhabitants ate well, enjoying a wide range of food including prime cuts of venison brought into the castle, probably mostly from the larger deer parks belonging to the earldom across the region.
