A series of unusual markings on the fireplace at Chesterfield’s Revolution House have been officially confirmed as protection marks designed to ward off witches.

The apotropaic markings (commonly referred to as anti-witch marks) depict a double ‘V’ which is a reference to the Virgin Mary Protector of Life and Family. Markings like this were usually placed near openings or windows with the intention of keeping witches and evil spirits out.

The unusual markings were spotted by one of the museum team who photographed them and sent the images to Professor Ronald Hutton, who kindly identified them.

Professor Ronald Hutton, a professor at the University of Bristol and leading authority on folklore, said: “These are convincing examples of apotropaic markings. The interlocked VVs are absolutely standard. The others are harder to make out but could correspond to more than one other known type of mark in the repertoire.”

Revolution House was originally constructed as a farmhouse in the 16th century and later became an inn during the 17th century – during this period there was a heightened belief in witches and witchcraft.

On Sunday 11 June Revolution House will be hosting a Witchcraft event. Visitors will be able to learn all about the 17th century witch hunts and get hands on to create their own witch pot.

Like apotropaic markings, witch pots were believed to protect your family and house from an attack by a witch’s curse and ensure you came to no harm.

Councillor Kate Sarvent, Chesterfield Borough Council’s cabinet member for town centres and visitor economy, said: “We already knew that Revolution House had a rich history but this is an interesting discovery that tells us more about the people who have used the building in the past.

“We’ve been planning the Witchcraft event for a while and this discovery makes it even more relevant – the event is set to be a great day out for everyone and I hope lots of you will come along and make your own witch pot.”

The Witchcraft event is free to attend but donations are welcome and takes place on Sunday 11 June between 11am and 4pm. Creating a witch pot will be a drop-in session and visitors will be treated on a first come first served basis.

Other events are planned at the house each month throughout the summer including the return of legendary Tudor Minstrel Dante Ferrara, a demonstration of the healing properties of herbs and a display showing a selection of the council’s collection of sketches and art by Joseph Syddall.
