Nine hundred years ago, foundations were dug for a great church in Exeter which would develop into the beautiful cathedral that still marks the heart of the city. It is distinctive among English cathedrals for its twin transept towers, and unbroken vault stretching from the entrance to the high altar, and the sheer profusion of carving of plants and animals throughout. Exeter is a heavenly garden in stone, and this new book, illustrated with specially commissioned photography, draws on archaeology, archives and imagery to explain what its builders in a surprisingly cosmopolitan city were trying to tell us about their understanding of the world, and the realm they envisioned beyond us.
