History+
The site of the current church was previously home to earlier houses of worship, including a Romanesque choir tower church dating back to around 1050. This was expanded in the Gothic style around 1352. Foundation remains of this expanded church, uncovered in 1983/84, are now marked at the northeast corner of the building by special paving and an information board. In 1793, the church had to be demolished due to structural defects and lack of space. The plans for the new building originally came from court councilor Alois Geigel. After his death in 1798, court architect Andreas Gärtner took over the construction management. Despite initial disagreements regarding the design, particularly the columns in the choir, which corresponded to the will of the deceased Prince-Bishop Franz Ludwig von Erthal, construction proceeded. Financial bottlenecks and the turmoil of the Napoleonic Wars led to several construction interruptions. With the support of King Ludwig I of Bavaria, the building was finally completed in 1834. The interior work took place in 1835/36 according to Mattlehner's plans. The consecration under its current name took place on August 10, 1836, by Bishops Johann Leonhard Pfaff of Fulda and Adam Friedrich Groß zu Trockau of Würzburg.
