The theatre is 780 metres above sea level. The name Ullarima, by which the city is referred to in the local language, is thought to be related to the city of Wallarima mentioned in Hittite inscriptions. Hyllarima-Ullarima Theatre appears to consist of a single level. As is the case with all early period theatres the cavea is more than 180 degrees to hug the stage building at its two extremities. No detailed excavation of the theatre has been conducted. Although there only appear to be four stepped radial ways, the possibility of a further two radial ways at the row ends gives a total of six. The orchestra has a radius of 30 feet. There is a large mass of rock nearby behind the uppermost row of benches. Considering that the rows could have been arranged as far back as this rock, on the surface of which there are hollowed out rooms, we arrive at an eleven row theatre. The rows are chipped to accommodate the curvature of the circle they are located on. This is a difficult application. The workmanship of the benches reminds us of that in the neighbouring theatre of Kyon, but in this theatre it is done with more care. As we find in theatres of the early period, this theatre built by the Carians now bears traces of architectural modifications made first by the Greeks and then the Romans. At the orchestra boundary there are remains of honorary seats with backboards.
Hyllarima-Ullarima theatre has a capacity of approximately 1,200 people according to site measurements.
