Walk through the Piazza della Repubblica today and you're standing on top of a literal ghost town. Most people think Florence started with the Renaissance. They see the marble statues and the red-tiled dome and assume the clock started around 1400. Honestly? That's not even close. If you’re asking how old is Florence Italy, you have to look past the fancy Medici palaces and dig into the mud of the Arno River.
The short answer is that Florence is about 2,085 years old. But "age" is a tricky thing in Italy. Do you count from the day a Roman soldier hammered in the first tent peg, or do you count from when the Etruscans were lurking on the hills above?
The 59 BC Myth and the Roman Blueprint
Basically, the Florence we recognize today—the actual street grid and the location—began in 59 BC. Julius Caesar needed a place for his retired veteran soldiers to settle down. He picked a spot where the Arno River was easy to cross. It was a strategic military move, plain and simple.
The Romans named it Florentia, which means "the flourishing one." It wasn’t a city of art back then. It was a castrum—a military camp.
You can still see this 2,000-year-old skeleton if you look at a map. The streets are remarkably straight in the center. That’s because the Romans loved their grids.
- The Cardo (north-south axis) is today's Via Roma and Via Calimala.
- The Decumanus (east-west axis) is Via del Corso and Via degli Speziali.
- The Forum? That’s exactly where Piazza della Repubblica sits today.
If you head into the basement of the Palazzo Vecchio, you can actually see the remains of a Roman theater. It's wild. People are up there debating politics or taking selfies, and just a few feet below them are stones laid by soldiers who probably knew Caesar personally.

Wait, Were People There Before the Romans?
Yeah, totally. This is where the "how old is Florence Italy" question gets messy.
Long before Caesar arrived, the Etruscans were the big bosses of Tuscany. They lived up in Fiesole, that beautiful hilltop town you can see from the top of the Duomo. They didn't really want to live down in the valley because it was marshy, buggy, and prone to flooding.
Archaeologists have found Villanova-era artifacts (we’re talking 9th and 8th century BC) in the area. So, humans have been hanging around the Arno for nearly 3,000 years. But as a formal, organized city? That’s a Roman invention.
The Dark Ages: When Florence Almost Disappeared
Florence didn't just grow in a straight line. It almost died. When the Roman Empire collapsed, the city went through a "dark" period that was actually pretty terrifying.
Between the 5th and 8th centuries, the city was a punching bag. Goths, Byzantines, and Lombards all fought over it. At one point, the population dropped to maybe 1,000 people. Think about that. A city that now holds millions of tourists was once basically a tiny village hiding inside crumbling Roman walls.
Things only started to turn around when Charlemagne showed up in 774. He spent Christmas in Florence, and suddenly the city was back on the map.
The Medieval Explosion (1115 AD)
If 59 BC was the birth, 1115 AD was the city’s "coming of age" party. This is when Florence became an autonomous commune. The Margravine Matilda of Tuscany died, and the Florentines basically said, "We’re in charge now."
This era is why Florence feels so vertical. Families built massive stone towers to protect themselves from their neighbors. It was a violent, chaotic, but incredibly wealthy time. By 1252, they were minting the gold florin.
The florin became the "U.S. Dollar" of the Middle Ages. It was the standard currency for all of Europe. When you have that kind of money, you start building big. They started the Duomo in 1296. They built the Palazzo Vecchio in 1299.
Timeline of Florence's Age
To keep it simple, here is how the layers of time actually stack up:
- 900 - 800 BC: Early Iron Age (Villanova culture) settlements appear near the river.
- 59 BC: Julius Caesar officially founds Florentia as a colony for veterans.
- 285 AD: The city becomes the capital of the Tuscia region.
- 541 AD: Sacked by the Ostrogoths; the city enters a long decline.
- 1115 AD: The Republic of Florence is born. This is the "Golden Age" start line.
- 1865 AD: Florence actually becomes the capital of the Kingdom of Italy for five years.
Why Does Its Age Matter?
Knowing that Florence is over 2,000 years old changes how you look at the buildings. The "Old Bridge" (Ponte Vecchio) isn't just old; the current version was built in 1345, but there’s been a bridge in that exact spot since Roman times.
When you see the Baptistery, you’re looking at a building that many Renaissance thinkers actually believed was an ancient Roman temple of Mars. They were wrong—it’s likely 4th or 5th century—but the fact that they thought it was ancient tells you how much the Florentines respected their own age.
Actionable Tips for History Hunters
If you want to see the "old" Florence that most tourists miss, do these three things:
- Go Underground: Book a tour of the Roman ruins beneath the Palazzo Vecchio. You can see the original "vomitoria" (exits) of the theater.
- Look for the "Old" Walls: Find the Via del Proconsolo. This street follows the exact line of the first Roman walls from 59 BC.
- Visit Fiesole: Take the number 7 bus. It’s a 20-minute ride to see the Etruscan walls and a Roman temple that predates almost everything in the Florence city center.
Florence isn't a museum; it's a living organism that has been recycling its own bones for two millennia. The stones you’re walking on have seen Caesar’s soldiers, Dante’s exile, and Michelangelo’s chisel. That’s a lot of history for one little valley.
