St. Luke's Church was built by Mauro Kacafrangi in 1195 of which is mentioned in the inscription on the western façade. This is a modest one-nave church whose main nave is longitudinally divided into three parts. St. Luka’s church has characteristics of the Romanesque and Byzantine architecture. This is the only building in the town which did not suffer any major damage during earthquakes. It was depicted with frescoes soon after its construction, of which remained only some fragments on the southern wall.
The church altar was the work of Dascal Dimitrije, the founder of the Rafailovic school of painting from the seventeenth century. Once this church was catholic, but later it was given to orthodox people to use. Thus the church has two altars – the catholic and orthodox. The church floor is made of tombstones of common tombs of Kotor citizens, as burials took place in the very church until 1930s.
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.
