The Pitched Stone Court forms the north-east corner of the castle, and provided a centre for the castle services and servants; it takes its name from the late-Tudor cobbling, or pitched stones. On the east side of the court is the former office wing, a 16th-century construction mostly destroyed during the siege of 1646. The castle kitchens and pantries are on the north side, containing two large fireplaces and storage facilities for food and supplies in their cellars. In the 1460s, the first floors to these buildings included chambers for the senior servants. The buttery in the north-west corner would have been used to store and serve beer and wine.
