Rome's Machelo Theatre. It is located south of Piazza Venezia and has a history of 60 years longer than the Colosseum. Although not as big as the Colosseum, but the head is bigger, the Machero Theatre was planned by Caesar, the first consul of the Roman Republic, after Caesar was assassinated, his nephew Octavian became the first emperor of the Roman Empire, Augustus the Great. In 11 AD, Augustus completed the construction of the theater and named it after his nephew, Machero, who originally had 20,000 seats and was a semicircle theater. In the 16th century, a palace house was built above the original theater building, now a high-end apartment. In Rome, there are many such "premier monuments" such as the Hadrian temple.
