The Pevsner Architectural Guides are a series of guide books to the architecture of Great Britain and Ireland. Begun in the 1940s by the art historian Sir Nikolaus Pevsner, the 46 volumes of the original Buildings of England series were published between 1951 and 1974. The series was then extended to Scotland, Wales and Ireland in the late 1970s. Most of the English volumes have had subsequent revised and expanded editions, chiefly by other authors.
