Triumphal Arch and back of Stage

When the theatre was erected there was no stage; this was added around AD 160. The theatre could accommodate several hundred spectators on simple wooden benches and had a section in front of the stage where town magistrates and local dignitaries were seated.

Around AD 180 a large monumental arch was erected. Point out base of triumphal arch. A triumphal arch is a monumental structure in the shape of an archway with one or more arched passageways, often designed to span a road. In its simplest form a triumphal arch consists of two massive piers connected by an arch, crowned with a flat top which a statue might be mounted, or which bears commemorative inscriptions.
