Visitation of Mary Church was already recorded on Rožnik Hill in a 1526 document, stating that it had to provide a copper chalice and three pounds of hellers for the war effort. This church was razed in 1740, and a new church was built in 1746 according to plans by Candido Zulliani (1712–1769) and consecrated by Bishop Ernest Attems (1742–1757) in 1747.
The church was damaged by artillery fire during the Napoleonic siege of Ljubljana, and after its 1814 renovation it was given a Neoclassical facade. Management of the church was taken over by the Franciscans in 1826, and in 1836 it was transferred to the order as a chapel of ease. New altars were installed in the church in 1895.
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.
