Theatre of Marcellus in Rome is reminiscent of the famous Roman Coliseum. This similarity is not accidental as the theatre of Marcellus was the point of reference for the builders of the Coliseum. The ancient Romans usually built their theaters using the natural terrain and placed them on the hillsides. Nevertheless, the theatre of Marcellus was erected on flat ground. In order to improve the acoustics its walls rise to a height of three floors. The theatre was built at the behest of Emperor Augustus, who thus wanted to honor the memory of Mark Marcellus. It could accommodate approximately 14,000 spectators.
