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 slate dial on the porch has a central circular finial with smaller diamond shapes at the sides. It declines East and shows VI - IIII undivided, unless the decorative ciphers in the chaper ring are meant to indicate the half hours. In the circular finial are the initials of the warden and the date 1707. Stars lie inside the diamonds. Scrolls and a star appear at the side of the sunburst which has lost its face, perhaps following the fitting of a new and rather crude gnomon which has been bent from an iron rod. The dial measures 450mmw x 680mmh.
