Amphitheatrum Flavium: the largest amphitheater of the ancient world, better known as Rome's "Colosseum".
The Jews who in 70 CE were conquered by Titus when he sacked Jerusalem, were transported to Rome, where they were forced to build the Temple of Peace and the world's largest Amphitheater, which was surnamed Colosseum after the Colossus of Nero that stood next to it. It was dedicated in 80, and remained in use for at least five centuries.
Early in the morning, the 50,000 visitors could see hunters and animal fights; at noon, criminals were executed; and in the afternoon, gladiators performed.
The monument was several times restored, but in the sixth century, the arena was converted into a cemetery, and churches were built next to it. During the Renaissance, the Colosseum was used as a quarry. The execution theater remains a popular tourist attraction.
