A collection of concise historical notices documenting Caen's lost or altered monuments and the city's former port. Each entry reconstructs the origin, architectural features, modifications, and circumstances of demolition or defacement for civic buildings, churches, abbeys, gates, and port works, often citing older chronicles or archival seals. The volume pairs text with five engravings based on watercolours and unpublished drawings, and gathers footnotes and errata compiled by the editor. Overall it blends antiquarian description, documentary quotations, and archaeological interest to trace how urban change and conflict reshaped local heritage.
