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 Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
