St. Stephen's Church is a protected cultural monument situated in Nitra. The beginning of the present-day church dates back to the 10th century. In the following two centuries, St. Stephen's Church was rebuilt. In early 18th century the church was renewed to its final Baroque style. This site is a rare medieval structure with the sanctuary beneath a Baroque semicircular vault with lunettes. You can still see parts of Romanesque frescoes inside. The church was rebuilt by František Maťašovský in 1720.
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.
