A petrifying well gives objects a stone-like appearance. If an object is left into such a well for a period of weeks or months the object acquires a stony exterior. Notable example of petrifying well in England is the spring at Mother Shipton’s Cave in Knaresborough where objects left suspended in the calcium-rich water are gradually turned to stone. For many centuries, locals believed that this petrifying well was cursed by the devil . The fact that the side of the well looked like a giant’s skull fueled their fears that they too would be turned to stone.The Knaresborough petrifying well was first opened to the public in 1630 and still amazes visitors to this day.
