Across England's medieval churches and barns, symbols long presented to the public as witches' marks — carved to ward off demons and invoke divine protection — are being reinterpreted by architectural historian Jennifer Alexander as something far more earthly: the geometric practice exercises of stonemasons and their apprentices. Her challenge, backed by a new scholarly work and presented at the International Medieval Congress in Leeds, invites us to consider how readily we project mystery onto the traces of ordinary human labor.

Minimal direct impact. Heritage tourists may experience slightly altered interpretations at historic sites, but this reframing is unlikely to affect visitor numbers or spending patterns. Educational content about historic buildings will be updated with more accurate information.
English Heritage and Historic England may need to revise interpretive materials and signage at 400+ sites. This could require modest reallocation of curatorial resources toward accurate historical documentation. May influence funding priorities for archaeological research and heritage education programs to emphasize evidence-based interpretation.
