Next: Wednesday, April 21, 2027 (expected)
Rome's birthday on April 21 draws costumed reenactors from across Europe, who parade toward the Colosseum and camp at the Circus Maximus with gladiator shows and ancient rites.
Natale di Roma marks the legendary founding of Rome by Romulus on April 21, 753 BC. The date has been celebrated on and off for nearly two thousand years: Emperor Claudius held an official anniversary in 47 AD, Philip the Arab marked the city's first millennium in 248 AD, Renaissance scholars revived it, and it was made an official holiday under Mussolini in 1924, a decree repealed in 1945.
Today it is a festival of historical reenactment. Costumed groups such as the Gruppo Storico Romano parade through the centre, and there are ceremonies, military bands and events spread over several days. It suits anyone curious about ancient Rome, and families who enjoy a costumed spectacle.

Every year on April 21, with related events often spread over several days around that date.
Watching the parade from the street is generally open to the public. Some related events may be ticketed; the sources don't list prices, so check the programme.
It is the traditional date of Rome's founding by Romulus in 753 BC.
Rome's ancient core runs from the Colosseum past the Forum to the white Vittoriano on Piazza Venezia, a few thousand years of history in a 20-minute walk.
Getting there: Metro line B stops at Colosseo, opposite the amphitheatre, and line C's new Colosseo–Fori Imperiali station opened beside it in December 2025. Piazza Venezia and the Vittoriano are a straight walk up Via dei Fori Imperiali.
