At one time, at the most prominent point along the road between Old Hurst and St Ives, there could be found a low chair-shaped hunk of stone called the Hursting Stone, or the Abbot's Chair. This glacial relic served many functions throughout the centuries, having been sculpted into a curious chair-shaped mass: folklore has it that it in the Middle Ages it formed the base of a plinth that held an almighty stone cross upright. Here, sentences were passed in open-air trials. Later it earned the name 'Abbot's Chair' from the belief that monks would sit in it and rest while travelling. This antiquity now rests against a wall just outside the Norris Museum in St Ives and, according to the writer Daniel Codd, there is a belief that it is haunted. There is also a belief that if the stone should ever sink beneath the earth then the streets of Bluntisham would run red with blood.
