NovaRomaNova Roma is an international organization dedicated to the study and restoration of ancient Roman culture. From its founding to 330 CE, when it ceased to be the center of Imperial authority, Rome laid the foundation for our modern Western civilization. Founded 2,750 years after the Eternal City itself, Nova Roma seeks to bring back those golden times, not through the sword and the legions, however, but through the spread of knowledge and through our own virtuous example.
