The Colosseum is the largest amphitheater around the world capable of hosting up to 50,000 spectators. Elliptical in shape with a perimeter of 527 meters and the axes 187.5 x 156.5 meters, the Colosseum was 52 meters high while today it reaches 48.5 meters.
The three lower registers of the external facade have 80 numbered arches while the internal arena measures 86 x 54 meters.
The original name of the Colosseum is Flavian Amphitheater as it was the emperors of the Flavian dynasty who built it.
If, in fact, the construction began under Vespasian in 72 AD, the Colosseum was inaugurated in 80 by Titus while the second son of Vespasian, the emperor Domitian made significant changes, creating among other things the undergrounds of the Arena.
The name “Colosseum” began to spread only from the Middle Ages and probably derives from the presence near the amphitheater of the “colossal” statue of Nero.
In 1980 the Colosseum was included in the UNESCO World Heritage List together with the entire historic center of Rome while in 2007 it was included among the 7 Wonders of the Modern World .
In addition to being the most famous and visited monument in Italy, in 2019 the Colosseum established itself as the most visited and popular monument in the world, according to the ranking of the number of reservations and approval rating drawn up, worldwide, by TripAdvisor. Behind the Colosseum were the Louvre in Paris and the Vatican Museums, while the Eiffel Tower took fifth place behind the Statue of Liberty in New York
