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.
Pair of vertical declining dials on the battlements above the porch.
The dials face southwest and southeast. Unfortunately they are in very poor condition with no visible markings. The faces are concave. This is so uniform that it looks like design, not erosion. If so it is most unusual and would have made inscribing hour lines very difficult.
The gnomons are also in a very bad state. The left (southwest) one is in position but very rusty. The right one has been broken since our photograph was taken.
The capstone over the dial is disintegrating.
The porch and battlements are early fifteenth century, so that may date the dial.
