The Colosseum is a huge, oval-shaped building in the center of Rome, Italy. It is the largest ancient amphitheatre ever built. Even today, it is the biggest standing amphitheatre in the world.
Construction of the Colosseum started around 72 AD under Emperor Vespasian. It was finished in 80 AD by his son, Titus. Later, Titus's brother Domitian made more changes. These three emperors were part of the Flavian dynasty. Because of this, the Colosseum was also known as the Flavian Amphitheatre.
The Colosseum was built using strong materials like travertine limestone, tuff (a type of volcanic rock), and concrete. It could hold between 50,000 and 80,000 people. People came to watch gladiatorial fights and other public shows. These shows included animal hunts, punishments, re-enactments of famous battles, and plays based on Roman mythology. For a short time, even mock sea battles were held there.
The building stopped being used for entertainment in the early Middle Ages. Over time, it was used for many different things. It became homes, workshops, a fortress, and even a Christian shrine.
Even though earthquakes and stone robbers damaged it, the Colosseum is still a famous symbol of Imperial Rome. It is one of the New 7 Wonders of the World. Today, it is one of Rome's most popular tourist attractions. It also has ties to the Catholic Church. Every Good Friday, the Pope leads a special procession called the "Way of the Cross" near the Colosseum. You can even see the Colosseum on the Italian version of the 5 euro cent coin.

What is the Colosseum's Name?
Originally, the building was simply called an "amphitheatre" in Latin. The name Flavian Amphitheatre is often used today. This name honors the Flavian dynasty emperors who built it. But the building is much better known as the Colosseum.
How the Name "Colosseum" Came About

The name Colosseum likely comes from a giant statue of Emperor Nero. This huge bronze statue showed Nero as a sun god. Emperor Hadrian later moved it next to the amphitheatre. The word colosseum means "gigantic" or "colossal" in Latin. By the year 1000, people started calling the amphitheatre "Colosseum" because of this nearby giant statue.
An old saying from the 8th century, linked to a writer named Bede, talks about the statue. It says: "As long as the Colossus stands, so shall Rome. When the Colossus falls, Rome shall fall. When Rome falls, so falls the world." People often mistakenly think this saying refers to the Colosseum building itself. But at that time, "Colossus" meant the statue, not the amphitheatre.
Over the centuries, the spelling of the name changed. In the 12th century, it was called the "Amphitheatre of the Colossus." Later, in the 14th and 15th centuries, similar names appeared in different languages. By the 1600s, the name Colosseum was commonly used in English.
The Colosseum's History
Building the Colosseum
The Colosseum was built in a flat valley between several hills in Rome. This area was once a lake and part of Emperor Nero's huge palace, the Domus Aurea. After Nero's death, Emperor Vespasian decided to build the Colosseum here. This was a popular move, as it gave back land Nero had taken for himself. Unlike many other amphitheatres, the Colosseum was built right in the city center. This showed its importance to Rome.
The money for building the Colosseum came from treasures taken after the First Jewish–Roman War in 70 AD. An old inscription says Emperor Vespasian used his share of the war treasures to build it. Many people, including slaves and prisoners of war, likely worked on the construction. Skilled Roman builders, engineers, and artists also helped. The Colosseum was made from wood, limestone, tuff, tiles, cement, and mortar.
Construction began around 70–72 AD. By the time Vespasian died in 79 AD, the Colosseum was mostly built. His son, Titus, finished the top level in 80 AD. The first games were held in 80 or 81 AD. Records say that over 9,000 wild animals were killed during these opening games. Emperor Domitian, Vespasian's younger son, later added an underground area called the hypogeum. This area had tunnels for animals and performers. He also added more seating at the very top.
Changes Over Time
In 217 AD, a big fire, possibly caused by lightning, badly damaged the Colosseum. It took many years to fully repair. More repairs happened in 250, 252, and 320 AD. Gladiator fights were banned in 399 and again in 404 AD. The last mention of gladiator fights is around 435 AD. Animal hunts continued until at least 523 AD.
During the Middle Ages, the Colosseum was used differently. A small chapel was built inside it. The arena became a cemetery. The arched spaces under the seats were turned into homes and workshops. Around 1200, a powerful family, the Frangipani family, used it as a castle. In the 14th century, Rome's population dropped, and the Colosseum became a place for bandits.
A major earthquake in 1349 caused a large part of the outer wall to collapse. Much of the fallen stone was reused to build other structures in Rome. People also took stones from the inside, and marble was burned to make quicklime. Metal clamps holding the stones together were removed, leaving holes you can still see today.
The Colosseum in Modern Times


In the 16th and 17th centuries, Church leaders tried to find new uses for the Colosseum. Pope Sixtus V (1585–1590) wanted to turn it into a wool factory. This idea did not happen. In 1671, a cardinal allowed bullfights, but public protests stopped it.
In 1749, Pope Benedict XIV declared the Colosseum a sacred place. He believed early Christians had been killed there. He stopped people from taking stones from it and made it a holy site. He also added Stations of the Cross inside. However, there is no clear historical proof that many Christians were martyred specifically in the Colosseum.
Later popes worked to fix and restore the Colosseum. They removed plants that were damaging the walls. The outer walls were strengthened in the early 1800s. The inside was repaired in the 1830s and 1930s. The underground area was fully uncovered in the 1930s.
Today, the Colosseum is one of Rome's most visited places. Millions of tourists come each year. A big restoration project happened between 1993 and 2000. Another major restoration, funded by a shoe company, began in 2013 and finished in 2016. This project cleaned and repaired the outer walls. Funds have also been set aside to replace the arena floor. This new floor will allow for cultural events. Since November 2017, the top two levels have been open for guided tours.
The Colosseum has also become a symbol against the death penalty. Since 2000, its night lights change from white to gold when a death sentence is changed or abolished somewhere in the world.
Because of its ruined state, the Colosseum cannot host very large events inside. But big concerts have been held just outside it, using the Colosseum as a beautiful background. Famous musicians like Paul McCartney and Elton John have performed there.
What Does the Colosseum Look Like?
Outside the Colosseum
Unlike many Roman theaters built into hillsides, the Colosseum stands completely on its own. It is shaped like an oval. It is about 189 meters (615 feet) long and 156 meters (510 feet) wide. The outer wall is 48 meters (157 feet) tall. The entire outer edge was originally 545 meters (1,788 feet) around.
The outer wall used over 100,000 cubic meters of travertine stone. These stones were put together without mortar, held by 300 tons of iron clamps. Earthquakes have caused much of this wall to collapse. The north side of the outer wall is still standing. The triangular brick supports you see at its ends are modern additions from the 1800s. The rest of the Colosseum's outside today is actually its original inner wall.
The remaining outer wall has three levels of arches. Above these is a tall attic level with windows. The arches on each level are framed by different types of columns: Doric on the first level, Ionic on the second, and Corinthian on the third. The attic level has Corinthian pilasters (flat columns). Statues of gods and heroes likely stood in the arches on the second and third floors.
Around the very top of the attic, there were 240 brackets. These held a giant retractable awning called the velarium. This awning protected spectators from the sun and rain. It was made of canvas and ropes, covering about two-thirds of the arena. Sailors from the Roman navy were specially trained to operate this huge awning.
The Colosseum needed to be filled and emptied quickly because of its huge size. It had eighty entrances at ground level. Seventy-six of these were for regular people. Each entrance and staircase was numbered. The main northern entrance was for the Emperor. The other three main entrances were likely for important people. Many outer entrances are gone due to the wall's collapse.
Spectators received tickets, which were numbered pottery pieces. These tickets told them which section and row to go to. People reached their seats through passages called vomitoria. These passages allowed people to quickly get to their seats and leave in just a few minutes.
Inside the Colosseum: Seating Areas
The Colosseum could hold about 50,000 people. Seating was arranged in levels, showing the different social classes in Roman society.
- Special boxes at the north and south ends were for the Emperor and the Vestal Virgins. These had the best views.
- Next to them was a wide platform for the senators. They could bring their own chairs. You can still see some senators' names carved into the stone.
- The next level up was for the non-senatorial noble class, called equites (knights).
- Above them, ordinary Roman citizens (plebeians) sat. This area was divided into two parts: a lower part for wealthy citizens and an upper part for poorer citizens.
- Specific sections were set aside for other groups, like boys with their teachers, soldiers, and foreign visitors.
- Stone or marble seats were provided for citizens and nobles. They probably brought cushions.
- The very top level was added later by Emperor Domitian. This gallery was for the common poor, slaves, and women. They either stood or sat on very steep wooden benches.
- Some groups, like gravediggers, actors, and former gladiators, were not allowed in the Colosseum.
Each level was divided into sections by curved passages and low walls. These sections were further divided into wedges by steps and aisles. Each row of seats was numbered, so every seat had an exact location.
The Arena and Underground Area
The arena itself was 83 meters (272 feet) long and 48 meters (157 feet) wide. It had a wooden floor covered with sand. The Latin word for sand is harena or arena, which is where the word "arena" comes from. This floor covered a complex underground structure called the hypogeum (meaning "underground"). The hypogeum was added later by Emperor Domitian.
Today, little of the original arena floor remains, but the hypogeum is clearly visible. It was a two-level network of tunnels and cages. Gladiators and animals were kept here before the shows. Eighty vertical shafts allowed animals and scenery to be quickly brought up to the arena. Larger platforms could even lift elephants. The hypogeum was changed many times over the years.
The hypogeum was connected by tunnels to buildings outside the Colosseum. Animals and performers came through tunnels from nearby stables. The gladiators' training school, the Ludus Magnus, was also connected by tunnels. Separate tunnels allowed the Emperor and the Vestal Virgins to enter and exit without going through the crowds.
Many machines were also in the hypogeum. Elevators and pulleys raised and lowered scenery and props. They also lifted caged animals to the surface. Some old stories say the arena could be quickly flooded for mock sea battles. However, when the hypogeum was built, flooding the arena stopped. Historians still debate how practical these sea battles truly were.
Buildings Around the Colosseum
The Colosseum and its events supported many other businesses nearby.
- To the east was the Ludus Magnus, a training school for gladiators. It had an underground passage to the Colosseum. The Ludus Magnus even had its own small training arena.
- Other training schools were also in the area, including one for animal fighters.
- The Armamentarium was an armory for weapons.
- The Summum Choragium stored machinery.
- The Sanitarium treated wounded gladiators.
- The Spoliarium was where dead gladiators' armor was removed, and their bodies were taken away.
Around the Colosseum, about 18 meters (59 feet) away, there was a series of tall stone posts. Five of these still remain on the eastern side. Their purpose is debated. They might have marked a religious boundary, an outer ticket check area, or anchors for the velarium awning.
What Was the Colosseum Used For?
The Colosseum hosted gladiator shows and many other events. These shows were usually paid for by wealthy individuals, not the state. They were very popular and showed off a family's power and importance.
Gladiator Fights and Animal Hunts
A major attraction was the animal hunt, called venatio. Many different wild animals were brought from Africa and the Middle East. These included rhinoceros, hippopotamuses, elephants, giraffes, Barbary lions, panthers, leopards, bears, Caspian tigers, crocodiles, and ostriches. Battles and hunts often took place with elaborate sets, including movable trees and buildings. Some events were huge. Emperor Trajan once celebrated his victories with contests involving 11,000 animals and 10,000 gladiators over 123 days.
During breaks, punishments were sometimes carried out. People sentenced to death might be sent into the arena, unarmed, to face wild animals. Acrobats and magicians also performed during intervals.
Mock Sea Battles and Natural Scenes
In the Colosseum's early days, some writers said it was used for naumachiae, or simulated sea battles. Accounts of the opening games in 80 AD describe the arena being filled with water. Special swimming horses and bulls were displayed. There was also a re-enactment of a famous sea battle. Historians debate how this was possible, as it's unclear how the arena could be waterproofed or if there was enough space for warships. It's thought that either the location was mistaken, or the Colosseum originally had a floodable channel that was later replaced by the hypogeum.
Sylvae, or recreations of natural scenes, were also held in the arena. Artists and technicians would build a forest with real trees and bushes. Then, animals would be brought in. These scenes might simply show nature to city people. They could also be used as backdrops for hunts or plays based on myths. Sometimes, these scenes were used for punishments, where a condemned person would act out a mythical story and be killed by animals or fire.
The Colosseum Today
In summer 2010, the underground tunnels of the Colosseum, once used for animals and gladiators, were opened to the public.
The Colosseum is also a site for Roman Catholic ceremonies today. For example, Pope Benedict XVI led the Stations of the Cross procession there on Good Fridays.
Restoration Efforts
In 2011, a shoe company owner, Diego Della Valle, agreed to fund a €25 million restoration of the Colosseum. The work started in 2013 and was the first full cleaning and repair in the Colosseum's history. The first part of the project, cleaning the outer walls, finished on July 1, 2016. The Italian Minister of Culture also announced that money was set aside to replace the arena floors by the end of 2018. These new floors will allow for "cultural events of the highest level." The project also includes creating a visitor center and restoring the underground spaces. Since November 1, 2017, the top two levels have been open for guided tours. The fourth level was a marketplace, and the fifth level was where the poorest citizens watched the shows.
The Colosseum and Christianity


Many Christians believe the Colosseum was a place where many early Christians were killed for their faith. This belief comes from Church history and tradition. However, some scholars think that most Christian deaths happened in other places in Rome, like the Circus Maximus. They say there isn't much physical evidence or historical records to prove many were killed specifically in the Colosseum. These scholars agree that some Christians were punished there for not worshiping Roman gods.
In the Middle Ages, people did not see the Colosseum as a holy place. Stones from it were taken to build other important sites. This suggests it was not considered sacred at that time. It was not listed in pilgrim guides as a place of martyrdom.
Pope Pius V (1566–1572) reportedly suggested that pilgrims collect sand from the arena as a holy item. He believed it was soaked with the blood of martyrs. A century later, Fioravante Martinelli listed the Colosseum as a sacred place for martyrs in his 1653 book. This book influenced public opinion. When a cardinal later suggested using the Colosseum for bullfights, there was a protest. This led Pope Clement X to close the Colosseum's outer arches and declare it a sanctuary.
At the request of St. Leonard of Port Maurice, Pope Benedict XIV (1740–1758) stopped the removal of stones from the Colosseum. He also put Stations of the Cross around the arena. These remained until 1874. Several popes in the 1800s funded repairs and restoration work. The Colosseum still has its Christian connection today. A Christian cross stands inside, with a plaque that says the amphitheater, once used for pagan worship, is now dedicated to the sufferings of martyrs. Other crosses are around the arena. Every Good Friday, the Pope leads a Via Crucis procession to the amphitheater.
Plants Growing at the Colosseum
The Colosseum has a long history of plants growing on it. The first list of its plants was made in 1643. Since then, 684 different plant species have been found there. The most were recorded in 1855, with 420 species. In 1871, people tried to remove the plants because they were damaging the stone. But many have grown back. Today, 242 species have been counted. About 200 of the species first identified in 1643 are still there.
The variety of plants can be explained by changes in Rome's climate over centuries. Bird migration also plays a role, as birds carry seeds. The growth of Rome itself also changed the Colosseum's environment. It is now in the city center, not on the outskirts. Animals brought to the Colosseum from across the Roman Empire also unknowingly carried seeds on their fur or in their waste.
