The Co-Cathedral of the Holy Cross is the co-cathedral of the Diocese of Bjelovar-Križevci. The church is mentioned in written sources as early as 1232. The church was rebuilt over the centuries. In its initial stage is the portal of the 14th century and the present appearance in the Gothic style of the 15th century. Are noticeable late, Renaissance Gothic in the belfry and facade of the sixteenth century and Baroque style, on the ship. The church was completely restored in 1913 by architect Stephen Podhorski.
On December 5, 2009, with the establishment of the Diocese of Bjelovar-Križevci, the church was elevated to the status of co-cathedral, under the Bull 'De maiore spirituali bono' of Pope Benedict XVI.
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.
