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:Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
