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 set on a wooden pillar inside the main entrance gate to the castle. It gives sun time at Greenwich, the time ring having been rotated to show 12:34pm at local noon to account for the longitude difference, and has a graph of the further correction needed to allow for the equation of time to get Greenwich Mean Time. It shows hours VI - XII - IV - VII, read from the outside, with a noon gap and divided to 30, 15 and 5 minutes. It is inscribed ’Whatever you do, do it with the zeal of a warrior and the sensitivity of an artist’, believed to be part of saying attributed to Shri Mataji Nirmala Devi, the founder of Sahaja Yoga Meditation.
