The Regimental Institute, which is located towards the southern end of the Castle complex, close to Cannons Gate, was constructed in 1868 as a canteen and recreational area for the soldiers, today it is used as a restaurant for visitors to the castle. The rooms were originally laid out with a bar, tap room, recreation room, and kitchens on the ground floor, and library and reading room on the first floor. By the end of the 19th century the building had been expanded to its present size and included a library and billiards room.

The Regimental Institute was conceived in a Tudor Gothic Revival style and still retains many original details. The building is of a similar design to many other non-defensive buildings constructed during the later 19th century. Situated on sloping ground, the building is two stories in height and formed of two blocks - the southern block having a basement due to the positioning of the building on sloping ground. The western elevation is the principal façade of the building and there is coat of arms detailing set over the principal entrance within a central gable. Similar in design to Salvin’s Officers Mess building, the Regimental Institute is constructed of polygonal rubble stone with ashlar stone dressings and a slate roof. The doors and windows have decorative stone hood moulds and the rubble stone elevations are broken up with string courses. summarised form sources (1-2)
