It was constructed at around 70 AD spearheaded by the Roman emperor Vespasian. It was only completed during the reign of Emperor Titus. The Colosseum was generally used for public events such as gladiator matches. These matches are comprised of gladiators who fought against other gladiators, criminals or wild animals. Other events held at the colosseum included mock sea battles, executions and animal hunts. During the medieval era, the use of the colosseum for public events ceased. Instead, it served such uses as dwellings, workshops and fortresses.

The colosseum condition has worsened due to natural disasters such as earthquakes. There have also been reports of stone-robbers taking away bits and pieces of the structure. However, it is still one of the most highly recognizable symbols of Ancient Rome. It is also a very popular tourist attraction to this day.

Aside from the amphitheatre, which played host to the gladiator matches back in the day, there are other attractions in the surrounding area. One such attraction is the remains of the Ludus Magnus, which is also known as The Great Gladiatorial Training School. As implied from the name, it was used as a training ground for the gladiators. Most of the area has been restored, such as the triangular fountains located within.

Other nearby attractions include the Armamentarium, which was an armory used to store weapons and defenses, the Summum Choragium, which was used to store machinery, the Sanitarium, which was used as place to treat wounded gladiators and the Spolarium, which was used to dispose of the dead gladiators and their various equipment.

The Colosseum is used today for religious purposes. Some Roman Catholic ceremonies, such as those involving Pope John Paul II, were hosted there. There are crosses littered in various areas surrounding the arena. During Good Fridays, the Pope typically leads a procession called the Stations of the Cross.

The Colosseum walls have large amounts of flora. There have been more than 600 different flora species discovered there. Previous attempts to remove the flora, due to concerns regarding damage to the architecture, have largely been unsuccessful as much of the flora eventually returned.

Common sights near the surrounding area of the Colosseum are men garbed in the traditional costume of the ancient gladiators. There are plenty of souvenir shops along the way as people are usually milling about from a leisurely stroll.

Today, the Colosseum is a highly visible structure due to its inclusion in a variety of media forms. Some movies, such as Gladiator or Jumper, use the Colosseum as a site for some of its scenes. Computer technology was used to restore the Colosseum to an approximation of its original state. The term colosseum is used for other entertainment facilities such as theatres and halls.
