The architectural design of Ancient Roman theaters were modeled after the theaters of the ancient Greeks. However, there are unique aspects of Ancient Roman theaters, that should be pointed out.

 The theater at Fiesole, Italy is typical of ancient Roman theaters in that the theater is not enclosed on all sides.

Like the Theater of Pompey, ancient Roman theaters had free standing foundations. Unlike Greek theaters, ancient Roman theaters were not built atop hills or high elevation grounds. The Theater of Pompey is also famous for being the place where Julius Caesar was killed.

Like the Theater of Marcellus, the opening of the theater showcased the natural settings of the theater. In the case of the Theater of Marcellus, the natural setting was the Tiber Island.
