The Vienna Central Cemetery (Wiener Zentralfriedhof) is one of the largest cemeteries in the world, largest by number of interred in Europe and most famous cemetery in Vienna. Unlike many others, the Vienna Central Cemetery is not one that has evolved slowly with the passing of time. The decision to establish a new, big cemetery for Vienna came in 1863 when it became clear that – due to industrialisation – the city's population would eventually increase to such an extent that the existing communal cemeteries would prove insufficient.
The cemetery was opened on All Saints' Day in 1874, far outside Vienna's city borders. Today there are over 330,000 graves.
The church in the centre of the cemetery is named Karl-Borromäus-Kirche (Charles Borromeo Church), but is also known as Karl-Lueger-Gedächtniskirche (Karl Lueger Memorial Church) because of the crypt of the former mayor of Vienna below the high altar. This church in Art Nouveau style was built in 1908–1910 by Max Hegele. The crypt of the Austrian Federal Presidents is located near the Dr. Karl-Lueger Memorial Church. Beneath the sarcophagus, is a burial vault with stairs leading down to a circular room whose walls are lined with niches where the deceased in an urn or coffin can be interred.
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.
