8 things you probably didn’t know about the Colosseum


Unlike other ancient theaters, the oval-shaped, freestanding amphitheater was a Roman invention. And, as the jewel in the crown of such imposing Roman-made architectural specimens, the Colosseum holds its head high with the towering elliptical tiers that rise to 180 ft (55 m) from the heart of the city. From those very seats, the ‘bloodthirsty’ audience watched on the impeccably choreographed mock battles, exotic animal parades and their merciless slaughtering, and even those ‘legendary’ gruesome gladiatorial fights. But there is more to this exalted arena, than just the collective ancient display of viciousness and pomp. So, without further ado, let us check out eight interesting facts that you may not have known about the one-and-only Colosseum.

Vital Statistics –


Being elliptical in plan, the Colosseum is 189 m (615 ft) long, and 156 m (510 ft) wide – which accounts for almost 500 m (1,640 ft) in circumference, with a base area of 6 acres (24,000 sq m). The inner arena is similarly oval, with length of 87 m (287 ft) and width of 55 m (180 ft); while being surrounded by a 5 m (16 ft) high wall on all sides – after which the seat tiers started. As we mentioned before, these tiers ultimately rose to a height of 180 ft (55 m) – thus making the total volume of the Italian amphitheater a whopping 1,320,000 cubic m or 47 million cubic ft. So, it comes as no surprise that during peak events, the Colosseum could hold up to even 80,000 people!

Amazing Facts –
1) Colosseum was built as a monument of victory for the Roman people, not the Emperor.


Some historians believe, the Colosseum (or as it was originally known ‘Amphitheatrum Flavium‘) was funded from the spoils taken from the Second Jewish Temple in Jerusalem, during the brutally suppressed Great Jewish Revolt in 70 AD. In any case, the massive endeavor was undertaken during Emperor Vespasian’s reign, to demonstrate the value of a ‘public’ landmark, as opposed to self-indulgent projects of his much-despised predecessor – Nero. Quite symbolically (and also practically), the site chosen for the humongous arena was previously an artificial lake that was a part of the absurdly opulent Golden House (Domus Aurea) that Nero had built fueled by his personal whim.

As a result, most of the expansive compounds along with gardens and pavilions were torn down by 69 AD, to make way for the monumental structure and other support buildings, like gladiatorial schools. The grand reclamation project did wonders on the political side of affairs, since the Roman citizens were satisfied and even honored (after the disastrous Great Fire of 64 AD) by the magnificent amphitheater. In many ways, the Colosseum represents the Roman celebration of military victories; but this time the ‘credit’ was heaped upon the Roman public, instead of the usual chosen cases of emperors and leaders.

2) Yet the name ‘Colosseum’ comes from Nero’s statue, and it supposedly had ‘magical’ qualities!


In an ironic turn of events, Nero still seemed have his revenge in death, since the name ‘Colosseum’ itself is derived from the ‘colossal’ statue of Nero that stood in close proximity to the massive amphitheater. Scholars believe this famous term came into popular usage by 10th century AD, replacing Amphitheatrum Flavium or Amphitheatrum Caesareum. Oddly enough, during the construction of the building, Vespasian didn’t destroy the huge piece of sculpture; rather he had the head replaced with that of Apollo (which also had a solar crown). Successive emperors kept on altering this head portion, while the main statue survived well onto the middle ages; and preserved with it a fair share of urban legends.

One of these prophetical legends put forth by the Venerable Bede, the English monk from 8th century, suggested that – “as long as the Colossus (Nero’s statue) stands, Rome will stand, and if it falls, so will Rome, and after that the rest of the world will follow.” Anyhow, the statue did eventually fall during the medieval times, possibly after being pulled down to make use of its precious bronze metal.

3) Colosseum was built from travertine stone and tufa, without the use of mortar.


The Roman prided themselves on their engineering skills, and the Colosseum served as the magnificent masterpiece that flaunted their craftsmanship. To that end, the entire building was constructed from over a volume of 100,000 cubic m of travertine stones and tufa (both are varieties of limestone, naturally deposited by hot springs). These stone blocks were placed without any mortar; instead the builders opted for more than 300 tons of iron clamps that could hold the components together. Unfortunately, most of the walls have collapsed, with the modern Colosseum’s exterior profile exhibiting what was actually the amphitheater’s massive interior wall.

And, since we are talking about collapsing and dilapidation, the ruins of the Colosseum paradoxically speak volumes about the high level of engineering that went into its construction. In fact, with so many natural calamities affecting the structure – which includes major fire damage from lightning and a series of earthquakes, it remains a wonder that any extant grand structural form is still standing proudly in the middle of Rome. To that end, at least six major renovation projects were carried out before 6th century AD, which equates to more than one repairing endeavor every century in the first 400 years of Colosseum’s existence!

4) The Colosseum’s advanced internal design was tailored to both crowd and animal control.


We have been harping about the core engineering values, but the deft internal layout of Colosseum is equally matched in sheer architectural aptitude. In that regard, the circulation pattern and the system of access points and corridors are astonishingly advanced for their age. These spatial arrangements were tailored to crowd control, and as a result, the amphitheater could easily manage over 50,000 loud, cheering spectators in a clockwork-like manner. Some of these user/space patterns can be surmised from the seating arrangement of the stadium, which segregated the visitors based on their societal background. For instance, the senators, the equites, the plebeians and the poor folk were all seated separately, while even more definite social groups – like small boys with their tutors, foreign dignitaries and soldiers on their leave were given special places to sit.

However, arguably more important was the control arrangement of wild animals – the regular attraction of the Colosseum. And, that is where the famed hypogeum came into the picture (image above the last paragraph), with its intricate double-leveled underground system of cages and tunnels that housed the animals and gladiators alike. These spectacle ‘participants’ were directly brought to the upper ground level arena via elevators – an effective design scope that had been showcased in a cinematic fashion in Ridley Scott’s ‘Gladiator‘. The hypogeum was also used for the purpose of stretching expansive awnings over the open-top of the amphitheater. These elaborate systems of pulleys, canvas, ropes and sockets were operated by actual sailors who were specifically recruited for the job.
