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 so-called horizontal dial here is nothing of the sort but it is worth inspection since it is an excellent example of what designers can produce when they are completely ignorant of any of the principles of dialling. It is of cast brass and was made this century. It has the embossed numerals I-XII equidistantly spaced with VI at the south. There are no hour lines and in the centre is a gnomon too small to be of much use. It carries no maker’s name as might be expected. Recorded only as a cautionary example, and in case it may some day be replaced with a proper dial.
