The Maltese Church is a Roman Catholic Gothic church of the Knights Hospitaller in Vienna. The first church on this site is mentioned in 1217, as a commandry to care and support crusaders. The current building was built in the mid-15th century. In the 17th century it was a favoured preaching location for Abraham a Sancta Clara.
This building was rebuilt to fit contemporary taste in the Baroque era and in 1806, and the Kommendenhaus (1839) and parts of the church (1857) had stained glass added during the 19th century. The Order ran into financial trouble after the First World War and in 1933 had to sell the church and the Johanneshof, and the church was given over to other uses within a historical preservation order. It was bought back in 1960 and restored in stages in 1968, 1972 and 1983-84, finishing with a general restoration in 1998.
The church's high altarpiece was painted in 1730 by Johann Georg Schmidt.
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.
