The mausoleum was built between 1860 and 1869 according to the plans of the Vienna architect professor Moritz Wappler, as a burial place for Archduke Johann of Austria and his family. The church is situated on an artificial terrace at the western edge of the church hill and is one of the earliest and without doubt the most successful sacred building in the Neo-Gothic style. The building was constructed of red sandstone and granite from the Ifinger region. In the underground crypt chapel with its heavy ribbed vaults, there is the marble sarcophagus of Archduke Johann and his wife.
