This map of Rome was included in an 1852 French Guide to Rome and it is based on a larger 1841 map by Paul-Marie Letarouilly (*); it shows Rome as it was before the development of railway and the 1870 annexation to the Kingdom of Italy; because it shows Rome in the last years of the Papal government, it is very useful to locate the monuments which house the papal coats of arms listed in the catalogue.
