The ancient Odeon of Thasos, an conservatory in the ancient city of Thassos was built in Roman times. The building, which was discovered in 1929 gives us the impssion of a monumental building even though its biggest part is under the modern road of the town with only its lower part visible and the first rows of seats. It is certain that in ancient times it would have been an imposing edifice. It is made of marble and situated in the south of the ancient Agora.
The building consists of a hollow with two rows of seats, forming a semicircle, one orchestra and a stage structure. The orchestra is not paved and from the byways survived the two walls that support the ground at the edges of the hollow.
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.
