A classic of architectural history and theory, Heavenly Mansions interprets architecture as a reflection of the age in which it flowers, and traces the alternating themes of fantasy and functionalism as exemplified in various styles and in the works of a number of influential men, including Wren, Viollet-le-Duc, William Butterfield, and Le Corbusier. Succinctly summarizing 800 years of viewpoints about architecture, it ranges from Gothic architecture to the Renaissance to the influence of modern abstract art on twentieth-century architecture.

"Each essay is a voyage of discovery. What is so interesting and what makes Mr. Summerson the architectural critic of his generation . . . is [an] aversion to dogma. . . . It is supremely well worth reading."-Spectator
