This survey‑guide work offers a combined historical monograph and brief guide to the city of Anagni in the Lazio region, Italy. Authored by Salvatore Sibilia, it traces the city’s development—from ancient origins through medieval papal prominence—to modern‑era civic identity. The book complements narrative history with visual and cartographic material (including approximately 50 illustrations and three topographical maps) to assist the reader in locating monuments and understanding the urban fabric. By combining academic history and tourist‑guide functionality, the text serves both local scholars and visitors interested in Anagni’s architectural, ecclesiastical and cultural heritage.
