Burnum was a Roman Legion camp and town. It is located 2.5 km north of Kistanje. The remains include a praetorium, the foundations of several rooms, the amphitheatre and the aqueduct.
It is assumed that Burnum originates from the year 33 BC, but it is more likely that it was established a few decades later. Several Roman legions were located there in succession, and the first one was Legio XX Valeria Victrix from the beginning of the Pannonian uprising (Bellum Batonianum) in AD 6-9. The reason for its location was the need for the control of traffic around the Krka River. Building was initiated by the Roman governor for Dalmatia Publius Cornelius Dolabella and continued by the Emperor Claudius.
The camp gained its final shape during the reign of Claudius around 50 AD. Legio XI Claudia Pia Fidelis left the camp some time between AD 42 and 67, probably AD 56-57 and was succeeded by Legio IIII Flavia Felix.
According to some sources, a rebellion of Lucius Arruntius Camillus Scribonianus against the emperor Claudius in AD 42 was started at this camp as well. After the last Roman legions had left the camp, it developed into an urban settlement.
The camp was completely destroyed when the emperor Justinian attempted to take it back from the Ostrogoths in the 6th century.
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.
