The accommodation and other facilities are on the south side of the castle.[49] On the ground floor, the entrance to the castle leads through to a courtyard, linked to four barrel-vaulted rooms in the south-west corner, originally 17th-century lodgings for the garrison.[50] Two of these chambers were converted for use as magazines and the fittings of one of these still remains in place.[50] In the south-east corner is the Master Gunner's House, comprising a parlour, hall and kitchen on the ground floor, and a chamber and attic on the floors above.[51] The parlour and hall would have originally been separated by a screen; the chamber would also have been subdivided.[52] On the first floor is a small chamber, supported on arches above the courtyard, which was used as a lodging.[53] On the second floor, the Long Room runs on top of the barrel-vaulted chambers, its massive, original roof still intact.[54]
