Not Built in a Day: Exploring the Architecture of Rome is a unique, unconventional guide and a deeply felt homage to Rome and its extraordinary 2,500-year history. Moving beyond the names, dates, and statistics of ordinary guidebooks, George Sullivan's eye-opening essays celebrate the special character of Rome's buildings, fountains, piazzas, streets, and ruins. From the largest landmark down to the smallest hidden gem, Not Built in a Day explores the city in comprehensive detail, offering detailed visual and historical analyses that enable readers to see and understand exactly what makes the architecture of Rome so important, influential, and fascinating.

Not Built in a Day is supported by a companion website (NotBuiltInADay.com) that offers, among other features, detailed illustrative photographs for readers who want to experience the book's walking tours at home and large printable maps for readers using small electronic devices on-site in Rome.
