St. Emmeram's Cathedral is a Roman Catholic cathedral located in the Nitra Castle precinct. It was originally built in the Gothic style and is composed of many parts. The upper church dates from 1333-1355. The rotunda dates back to the 11th-12th century and houses a silver reliquary made in 1674. Another reliquary in the cathedral houses some relics of Saint Cyril. The lower church was built between 1621-1642. Later on the entire cathedral complex was remodelled in the Baroque style.
Saint Emmeram of Regensburg, to whom the cathedral is dedicated, was an itinerant bishop who did missionary work from the court of the duke of Bavaria, Theodo I.
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.
