The Roman Theater of Nicopolis is characterized by the unique blend of elements of Greek and Roman architecture. The theater’s cavea stretches both on the natural slope of the hill, according to Greek standards, as well as on stone-built infrastructure, according to the Roman retaining system. Three successive semi-circular vaulted galleries of increasing height from the inside to the outside were constructed to position the upper part of the cavea. The outside gallery was inaccessible, while the two internal ones were also used as walkways of visitors. Arounbd the cave from the outside – for the monument’s best protection – a tall curved wall was built, which was periodically reinforced with struts to resist the compression of the construction. At the ends and in the middle of that wall were three entrances to the cavea. In the upper part of the cavea, a perimetric gallery with openings and niches was formed.
The orchestra, like the hollow, had the shape of a regular semicircle. On the façade of the two-storey stage building there were three apse-shaped entrances.
