The Colosseum is a monument with impressive history and it is Rome’s biggest treasure. Even today, the stadium is really magnificent and it is seen by a huge number of tourists. The Colosseum is the biggest amphitheater, found in the center of Rome, on top of Nero’s palace. It was made about 70-80 AD and it was started by Vespasian and finished by his son. In 80 AD, Vespasian’s eldest son Titus officially opened the Colosseum with 100 days of games, which included animal fights and gladiatorial battles. The amphitheater was significant due to the fact that it held a various events – both important and entertaining. It was designed for public spectacles and gladiatorial duels. Romans needed this because it entertained them and kept the lower class under control. One of the most famous types of show was the venatio. This is kind of entertainment in Roman amphitheaters that involves killing and hunting wild animals. Moreover, the Colosseum was place where a lot of public executions happened. The immense majority of the battlers who faced each other in front of the audience were men. The gladiators were mostly criminals, slaves or prisoners. Next, the Colosseum’s technology is really magnificent. It could hold 80 000 people. About its architecture, the theatre was also breathtaking from the outside with huge open arcades on each of the first three floors were statue-filled arches. Unlike the other amphitheaters, the Colosseum was a structure made of concrete and stone. Also it has perfect acoustic. The theater has many tunnels and trap doors from where the gladiators and the animals came from. It had retractable roof and universal parts. “Each entrance was marked by huge porticoes, each had gilded horse-drawn chariot on the top. The emperor also had a private entrance, which was under the seats, and went to the imperial box” (Keith Hopkins 2011). Unfortunately, the stadium had been damaged by natural phenomena such as earthquakes. In the later centuries, the Colosseum was abandoned completely and now used as a tourist location.
