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.
Located in roof line castellations. An apparently blank dial plate with painted numbers on the stonework outside - possibly a later innovation. Upright white sans-serif hour numerals VII - IIII. Noon is marked with a square box and 4pm as IIII. Long thin rod gnomon with unusual support formed by a second rod to the tip, itself with a short stay near its foot. Declination is E.
