An Amphitheatre Like No Other
Even after nearly two millennia, the Colosseum commands attention. Rising 48 metres above the heart of Rome, this elliptical amphitheatre was the largest ever built in the ancient world — capable of holding somewhere between 50,000 and 80,000 spectators. It is a feat of engineering that engineers today still study with admiration.
Building the Colosseum: How It Was Done
Construction began around 70 AD under Emperor Vespasian and was completed in 80 AD under his son Titus. The scale of the undertaking was extraordinary:
- An estimated 100,000 cubic metres of travertine limestone was used for the outer walls
- Concrete, tuff (volcanic rock), brick, and timber all played structural roles
- A sophisticated system of vaults and arches distributed load — allowing the enormous structure to stand without the steel we'd use today
- A retractable canvas roof (velarium) could be extended by sailors to shade spectators from the sun
The workforce included Roman soldiers, freed labourers, and enslaved people — many of them Jewish prisoners brought to Rome following the siege of Jerusalem in 70 AD.
What Happened Inside
The Colosseum hosted a variety of spectacles over its four centuries of active use:
Gladiatorial Combat
The most iconic events were gladiatorial bouts — highly choreographed contests between trained fighters. Gladiators were not always enslaved people or prisoners; some were volunteers drawn by the fame and financial reward the profession could bring. Bouts to the death were less common than popular imagination suggests — skilled gladiators were expensive to train.
Animal Hunts (Venationes)
Wild animals — lions, tigers, elephants, bears, rhinos — were brought from across the empire to be hunted by venatores (beast hunters). The underground hypogeum, a complex network of tunnels and cages beneath the arena floor, housed animals and machinery used to raise them dramatically into the arena.
Public Executions and Naval Battles
The arena was occasionally flooded to stage mock sea battles (naumachiae) in the early years. Later, the underground hypogeum made flooding impractical. Public executions of criminals and enemies of the state were also staged here.
The Colosseum After Rome
When the Western Roman Empire collapsed in the 5th century, the Colosseum fell into disuse. Over the following centuries it was repurposed: as a fortress, a quarry (much of its stone was removed for other building projects), and even housing. By the medieval period, it had become overgrown and partially ruined.
The Catholic Church eventually protected the site, declaring it sacred ground in memory of Christians allegedly martyred there — though historians debate the extent of this. Today it stands as Italy's most visited cultural monument and a UNESCO World Heritage Site.
Visiting the Colosseum Today
| Ticket Type | What's Included |
|---|---|
| Standard Entry | Ground floor and upper tier viewing galleries |
| Full Experience | Arena floor access + Roman Forum + Palatine Hill |
| Underground Tour | Hypogeum tunnels beneath the arena (guided, must book) |
| Gladiator's Arena | Special access to the central arena floor |
Tip: Book tickets online well in advance, especially in summer. Queues for walk-up tickets can exceed two hours. The Colosseum is most atmospheric at dawn or dusk, when the light turns the stone a warm amber.
Standing Before It
However many photographs you've seen, nothing quite prepares you for standing in front of the Colosseum in person. It is one of those rare places where history has genuine physical weight. The scars, the missing sections of outer wall, the worn stone — all of it tells the story of an empire that shaped the world we still live in.
