BRIDOL is the British Sundial Society's Register of Fixed and Mass Dials, which gives detail and photographs of about 8000 fixed sundials and 3000 mass dials in the UK.
Some of these are in private gardens, but the majority are publicly available.
The dial is mounted on the south-west corner of the tower at the east end of the frontage of the castle, on a level with the base of the first floor windows. It is held in the hands or claws of a figure which may be a man or a lion, on an octagonal base stone which sits on the shoulders and head of a monk, well carved and well preserved. The rather eroded thick dial plate is shield-shaped, with Arabic numerals for 6am to 6pm in a ribbon around the sides and base. Hour lines run to a semi-circle around the base of the gnomon which is missing. There has been an inscription around the curve of the semi-circle, not now legible.
