A heavy stone attached to a chain, a mystery. Who would lift it up and take it away? Seen in Utrecht.
The story behind is that the stone is there already since 1520 and was meant to protect the house against damage caused by towing goods or riding carts with big wheels.
There was also a legend that when you put a needle in it at 12 at night, some blood came out.
Also at night the stone was visited by all kinds of evil spirits, giants, witches and wizards.
They marbled with the stone over the boulders of the Old canal. They bounced it as a ball back and forth from one bridge to another. The inhabitants couldn't sleep anymore and they held a noctural procession and managed to banish all the evil spirits. To be on the safe side the stone was attached to a chain.
