St. Catherines Church stems from the 14th century and was built in the Romanesque-Gothic sstyle, which was typical of the sacral religious and scular architectural heritage of Old Bar. It represents a rare example of the churches of this period built above a vaulted passage.
The flat wall surface chiselled from grey and red alternating limestone found in local stone quarries nearby leaves the impression of having a representative quality despite being modest in size.
The windows were narrow, framed with thin slanting marble monophores facing west.
It is complettely unknown who the church belonged to. It is very difficult to determine whether it was built as a monastery for a monastic community or whether it was a private chapel within a palace.
