Medieval graffiti that people once carved to try and ‘ward off evil spirits’ has been discovered by archaeologists.
Two stones from the remains of a church in Buckinghamshire in the UK had the spooky lines etched into them.
Experts think they are 12th Century “witches’ marks”.
These marks look a bit like a circular web filled with lines and drilled holes.
Historians think medieval people wanted to trap evil spirits within the web or maze they had drawn.
