Roman theatre (structure)

However, Roman theatres have specific differences, such as generally being built upon their own foundations instead of earthen works or a hillside and being completely enclosed on all sides.

[citation needed] Their design, with its semicircular form, enhances the natural acoustics, unlike Roman amphitheatres constructed in the round.

[1] These buildings were semi-circular and possessed certain inherent architectural structures, with minor differences depending on the region in which they were constructed.

The cavea was sometimes constructed on a small hill or slope in which stacked seating could be easily made in the tradition of the Greek theatres.

The center of the cavea was hollowed out of a hill or slope, while the outer radian seats required structural support and solid retaining walls.
