The Roman theatre in Bosra, Syria. But there’s a relevant difference between Greek and Roman theatres: whereas the seating section of the former was wooden and built on a slope, or carved in stone, the latter had their own foundations, therefore the auditorium, too, was made of bricks and had galleries and openings.
Greek Theaters were carved out of a hillside while Roman theaters were built up from solid ground using either cement or stone. Also the orchestra is larger because the structures were used for other events which required more space.
