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.
Aligned Roman numerals read from inside a circular arc, IIII - XII - IIII - VI. Hour lines to circular arc around gnomon root. The dial is canted out 10 deg on the left hand side to face south. The chapel is claimed to be ’the oldest in Wales’. Ref http://www.churches-uk-ireland.org/powys/glasbury.jpg, accessed 20090319.
