2026 Pro Tip: Book your tickets ahead to see the most authentic history. Especially, travelers should book Underground (Hypogeum) tours to see the original 1st-century brickwork where gladiators once waited.
How Old is the Colosseum in 2026?

As of 2026, the Colosseum is 1,946 years old. This calculation comes from the year the gates first opened to the public. To be very specific about it, construction began around 72 AD, and the grand opening happened in 80 AD.
This place did not start with the name we use today. The builders called it the Flavian Amphitheatre or the Flavian Amphitheater. It was named after the family of emperors who decided to build it.
While nearly 2000 years have passed, it still feels like the heart of the city. The Colosseum was named one of the New 7 Wonders of the World in 2007 following a global public vote.
The Flavian Timeline From Vision to Inauguration
The Colosseum was built as a large public amphitheater on the site of Nero’s former palace complex. The Flavian emperors transformed the area into a public monument where Romans could attend games and spectacles.
The story of the building is actually a bit of a political drama. Before the stadium existed, the land belonged to Emperor Nero. He had built a massive private lake and a gold palace for himself (rather than serving his people, alas!!).
After he was gone, the new Emperor Vespasian wanted to do something to win back the people. He decided to drain Nero’s lake and build a massive public amphitheater right on top of it.
This bold move was a gift back to the citizens. Construction moved at a speed that would be impressive even today. In fact, construction began in 72 AD, the amphitheater was inaugurated by Titus in 80 AD, and further work was completed under Domitian around 82 AD. Vespasian passed away before he could see the finish line, but his son Titus made sure the job was done.
When the doors opened in 80 AD, they held a 100-day festival. It was a massive party with events that changed the history of entertainment forever.

Why the Colosseum is Still Standing

You might wonder how a building survives for almost two thousand years without falling apart. The secret lies in the materials and the genius of the engineers. Such as:
- The Romans used a specific type of limestone called travertine. They moved over 100,000 cubic meters of this stone from a quarry near Tivoli.
- They also used a very early version of concrete and volcanic rock. The design is full of arches to support an incredible amount of weight. The Colosseum had 80 entrances at ground level, with 76 numbered arches and four main entrances that were not numbered.
- If you look at the walls today, you will see thousands of little holes. Some people think these were made by bullets or war. The truth is, during the Middle Ages, people dug out the iron clamps. Even without those iron clamps, the building stands as a true marvel of engineering.

Who Built the Colosseum?
The Colosseum was begun under Emperor Vespasian around 72 AD and inaugurated by his son Titus in 80 AD. Further work was completed under Domitian, making the Flavian emperors collectively responsible for the monument’s construction and development.
Survival Against All Odds – Earthquakes and History
The building has not had an easy life. It has survived fires, lightning strikes, and several huge movements of the earth. The most famous incident was a massive earthquake in 1349. This event caused the entire southern side of the outer wall to collapse. That is why the building looks uneven today.
After that happened, the ruin was used as a sort of hardware store. Local builders would show up with carts and take away the fallen stone. They used that stone to build churches and palaces across Rome. It was only later that the church declared the site sacred. Then, finally, people stopped taking it apart piece by piece.

Discover Colosseum’s Most Historical Sides
The best place to see the original Flavian work is in the underground area or the hypogeum. This was the backstage of the gladiatorial games. The underground levels supported the machinery used to bring people, animals, and props into the arena. You can still see the brickwork from the 1st century down there.
Another amazing spot is the newly restored top level. From the attic you can see the entire footprint of the stadium. It gives you a sense of how the Romans managed to fit 50,000 people into one space. It is also where you can see the traces of the ancient water systems used for naval battles in the early years.
This tour is the best way to see the parts of the building that most people miss. You get to walk where the warriors walked and see the engineering secrets of the underground tunnels.
FAQs: Detailed Timeline of the Rome Colosseum
Is the Colosseum the oldest building in Rome?
No, it is not the oldest. The Theater of Marcellus is about 100 years old and looks quite similar. The Pantheon is also extremely old, but its current form was finished a few decades after the stadium.
Why are there so many holes in the stone?
Those holes were made by people in the Middle Ages who were looking for the iron and bronze clamps that held the stones together. They recycled the metal from the stadium.
Can you still see where the gladiators fought at the Colosseum?
Yes, you can see the arena floor. Much of it has been reconstructed so you can stand on top of the underground tunnels. It gives you a great view of where the action happened.
How many people died in the Colosseum?
It is estimated that over 400,000 people and over a million animals lost their lives there over the centuries. It was a place of extreme violence but also extreme skill.
Did they really have sea battles in the arena?
They did in the very early years. They would flood the base of the building with water and bring in boats. They stopped doing this once they built the permanent underground tunnels because those took up all the space.
Walking Through History
At the end of the day, knowing how old the Colosseum is is just the beginning. The real magic happens when you stand at its center and realize that almost 2,000 years of human history have unfolded on that very spot.
