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.
This Portuguese stone globe dial with raised continents weighs approximately 350 lbs. The stainless steel gnomon is swung to minimise the shadow, indicating the time with Arabic numerals on the hour ring.
