The monograph is a historical and archaeological essay. The author describes the main architectural monuments of ancient Rome - temples of the gods and palaces of emperors. Particular attention is paid to the most important archaeological finds made on the Forum and the Palatine Hill. Separate chapters are devoted to Christian necropolises (including catacomb burials) and the villa of Emperor Hadrian. In the last part of the work we are talking about Ostia - a city that was necessary for the existence of Rome.
