It said the find was made on Koulmou hill toward the end of 2015.
The ministry notes that archaeologists knew very little about the theater, which was not mentioned in any ancient sources, though the logs of an early 20th-century archaeological excavation under the direction of German archaeologist Ε. Κrüger, lasting only a few days, recorded the discovery of signs indicating the presence of an ancient theater.
Greek archaeologists confirmed the existence of the theatre and uncovered rows of seats, parts of the orchestra and some of the retaining walls for the stage.
The ministry said that the seats carved from the rock, are about 0.73 to 0.90 metres deep and 0.22-0.33 metres high.
The culture ministry said that continuing the excavation in order to reveal and protect the monument will be a priority.
