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.
Two balls are set up on square stone shafts on either side of a path on the garden terrace. They are marked with the equator, ecliptic and horizon. They are set uo 9° west of the N-S line and not quite level.
