Natale di Roma ("Rome's Birthday") is an annual festival held each spring commemorating the legendary founding of the city, traditionally dated to 753 BC, with several days of events centered around the city's ancient landmarks.
What happens
The festival typically includes costumed historical reenactment groups depicting gladiators, legionaries, and ancient Roman civic life, along with parades and events staged near sites like the Circus Maximus and the Roman Forum.
It's a local celebration too
Beyond the historical reenactments, Natale di Roma is treated as a genuine civic celebration by Romans, with fireworks and public events marking the occasion each year.
Worth checking dates in advance
Because it's organized annually with a published schedule closer to the date, checking the city's official events calendar ahead of a spring trip is the best way to catch any of it.
