Churches are many things to us - they are places of worship, vibrant community hubs and oases of calm reflection. To know a church is to hold a key to the past that unlocks an understanding of our shared history. Andrew Ziminski has spent decades as a stonemason and church conservator, acting as an informal guide to curious visitors. 'Church Going' is his handbook to the medieval churches of the British Isles, in which he reveals their fascinating histories, features and furnishings, from flying buttresses to rood screens, lichgates to chancels. Beautifully written and richly illustrated, it is a celebration of British architectural history.
