Colosseum is located near the ancient Roman market in the center of Rome. It was originally named Flavi amphitheater. It was built between 72 and 80 ad. it is a miracle in the architectural history and represents the most obvious characteristics of ancient Roman civilization.
The Colosseum is oval, covering an area of about 20000 square meters, with a long axis of about 188 meters and a fence of about 57M high, which can accommodate nearly 90000 spectators. Inside, you can watch each part along the tourist plank road. The auditorium is stepped, and the outermost layer is the arcade, which is the rest area for the audience before entering the venue. The modern gymnasium design is completely based on this.
The thick and thick arcades display the sculptures of the time. The bottom of the Colosseum is a trench type feeding area, a fight preparation area, and a water channel. Now it is completely exposed and sorted out. Before, it was covered with a wide fighting platform. Although only half of the remains of the Colosseum are left, it still shows its majestic power.
