Natale di Roma
Natale di Roma (lit. 'Birthday of Rome') is an annual festival held in Rome on April 21 to celebrate the legendary founding of the city. According to legend, Romulus is said to have founded the city of Rome on April 21, 753 BC. A Roman chronology derived its system, known by the Latin phrase Ab urbe condita, meaning 'from the founding of the City', from this date and counted the years from this presumed foundation.
