A building now known as the "Old Court" is south of the courtyard. Along with the North range and gatehouse most of the buildings were arranged around a central courtyard. The chapel is east of the rest of the buildings close to the River Exe. Moat Cottage is north of the other buildings. Gatehouse The gatehouse dates from the early 12th century and is a Grade I listed building. It is a three-storey single-depth plan stone structure with an asbestos slate roof surmounted by turrets. A central carriage archway leads into a courtyard. The building was substantially altered in the 15th century by the Courtenay family, and restored in the 1920s and 1930s during the ownerships of Mr Francis Harper and Lt Col Jasper Henson. The Sanctuary of the chapel pre-dates the Norman additions and alterations. The first documentary evidence of this building is circa AD600 probably before the Saxons arrived circa AD 660, with further documentary reference to it being a chapel circa AD800s. The Sanctuary is the oldest part no doubt altered during that time. There is archeological evidence of a wall at the west end of the Sanctuary with an arch, dividing it from the then nave. This was demolished when the nave was enlarged and replaced with a wooden Rood Screen. The current "wagon roof" dating from the 15th century. It is often cited as the oldest complete building in Devon. It was substantially renovated in the early 20th century. The rood screen was unfortunately lost during the 19th century when the Chapel was temporarily used to house cattle. The Chapel currently (2017) enjoys the benefit of a recently restored Estey organ dating from 1884. Old Court The Old Court is south of the range around the courtyard. It was built in the mid-fifteenth century as a Magistrates' Court for Thomas, the 6th Earl of Devon, who was executed after the Battle of Towton in 1461; however, it has been revised and added to many times and part of the structure may have been demolished. It may have formed a hall house covered by a five arch braced jointed truss cruck roof. After the English Civil War, when the Castle was severely damaged, it became a residence, and may well have had some of the alterations made at that time. It is believed an underground passage connects the Old Court to the Keep Gatehouse at a
