The smaller Roman Theatre of Pula from the 1st century AD was erected on the slope underneath the Venetian fortress. The area was divided into the stage and the proscene where the acting took place, the orchestra and the viewing area or the cavea. The theatre lied on the hill slope, which was the characteristic of Greek theatres. Only the stage foundations and a part of the semi-circular viewing area of the Small Roman Theatre have remained preserved. During the Antiquity, the theatre occupied a larger space not visible today in view of never completed archaeological surveys. Its capacity was estimated between 4 and 5 thousand spectators, which was the entire population of Pula at the time. Today, as in the Roman times, the twin gates lead to the theatre. In front of it is the Archaeological Museum, once the site of the German high school.
References:The ancient Argos Theater was built in 320 BC. and is located in Argos, Greece against Larissa Hill. Nearby from this site is Agora, Roman Odeon, and the Baths of Argos. The theater is one of the largest architectural developments in Greece and was renovated in ca 120 AD.
The Hellenistic theater at Argos is cut into the hillside of the Larisa, with 90 steps up a steep incline, forming a narrow rectilinear cavea. Among the largest theaters in Greece, it held about 20,000 spectators and is divided by two landings into three horizontal sections. Staircases further divide the cavea into four cunei, corresponding to the tribes of Argos A high wall was erected to prevent unauthorized access into the theatron and may have helped the acoustics, but it is said the sound quality is still very good today.
Around 120 CE, both theaters were renovated in the Roman style.
