Taper burn marks are deep flame shaped scorch marks often found on the timber beams of early modern houses.[1] They were originally thought to have been accidental scorches from a taper candle, but research suggests that most marks may have been made deliberately, as there is clear patterning of the activity.[2] They are theorised to have been made as part of a folk superstition, then thought to protect the building from fire and lightning.[1]
They are often found around entrances to the home such as fireplaces, doors and windows.[3]
Over 80 such marks have been discovered in the Tower of London.[4]
