Jon Cannon (1962 - 2023), architectural historian, lecturer and Canon Historian for Bristol Cathedral, worked for the Royal Commission on the Historical Monument of England and English Heritage. He is the author of several highly acclaimed books, including Cathedral: The Great English Cathedrals and the World that Made Them (Constable, 2007), The Secret Language of Sacred Places (Duncan Bird Publishing 2013) and Medieval Church Architecture (Shire Publications 2014). Jon also presented the TV documentary How to Build a Cathedral on BBC4 (2008).
Jon lived with his family on the chalk downs of Wiltshire, from which he wrote, taught and thought about place, sacredness and architecture. Jon died in May 2023. For more than a decade, Jon was 'Keeper of the Fabric', then 'Canon Historian', at Bristol Cathedral, and his memorial, carved into the fabric of the Cathedral's Berkeley Chapel, recognises his significant contribution to the building, and his wider contribution to the understanding and appreciation of religious buildings. Jon wrote: 'I have a vocation, and it's to do with places; with communicating, enthusing, analysing - in short, extolling - about the nature of "old places", and what makes them tick.'
