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 on a south facing buttress close to the door. The black hour lines & gold numbers are painted on a light blue ground. Shows hour lines from 7am to 6pm with half hours marked by fleurs de lys (or possibly crosses). The Roman numerals 10am to 3pm are aligned with the hour lines the rest are orthogonal to them. Uses XII for noon and IIII for 4pm.
At the gnomon root there is a sun with 16 ’flames’. The zodiac markers in the left and right borders are all that remain of the seven gold declination lines that were originally visible.
The present gnomon, with no nodus, appears to be supported by guy wires or very fine rods.
The motto reads: ’ΚΑΙΡΟΝ ΓΝΩΘ’, which is Greek for ’Know the Season’ (or ’Know the [right] time’ or ’Recognise the [right] moment’)
