The Pförringer Church, originally consecrated to St. George, is mentioned in writing for the first time in a document from 1031. Already in 1007, in the year of its foundation, Emperor Heinrich II had transferred the manorial rule "Horsingun" (Pförring) to the diocese of Bamberg. Around 1180 the Bamberg cathedral chapter built a three-aisled basilica consecrated to St. Leonhard with a transept in the west, three apses and two east towers. This was largely destroyed in a major fire in 1554.
The choir head with its three apses, the lower floors of the two towers and parts of the three portals that were reinserted in the new building have been preserved from the Romanesque church building. During the reconstruction after the fire, a single-nave nave was built and the upper floors of the towers were added. The former connecting bridge on the top floor between the two towers has not been preserved.
In 1711, due to the risk of collapse, the vault was removed and replaced with a flat ceiling. At the same time, the nave was extended by nine meters to the west and redesigned in the Baroque style. In the years 1896/97 the upper floors of the tower had to be demolished and renewed due to disrepair. In 1903 the nave was extended by nine meters.
