The Skopje Aqueduct is the only aqueduct in Macedonia, and one of three largest and well preserved in the former Yugoslavia.
The question of when the Skopje Aqueduct was built is unclear. There are three theories, it may have been built during the reign of Rome (1st century), during the reign of Byzantine Empire (reign of Emperor Justinian I) or during the reign of Ottoman Empire. According to this latest theory the aqueduct was built in the 16th century for the many Turkish public hamams.
This aqueduct was in use until the eighteenth century. Only about 386 meters with 55 arches of this structure of stone and brick remain.
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.
