The building was donated in 1429 as a benefactor's house by Duke Ludwig the Bearded of Bavaria-Ingolstadt, whereby the poor housed there were supposed to pray for the Duke's salvation. Construction began around 1434, with a dendrochronological analysis of the roof structure resulting in a date of 1435/36. With the foundation, the Bishop of Eichstätt was granted the right to use the building for other, more beneficial purposes.
There had been plans to found a university in Bavaria since 1458. When it was built by Louis the Rich in 1472 with papal privilege, the pope and bishop came back to the possibility of an alternative use for the benefice house and donated it to the young university. From 1472 the Pfründnerhaus was converted into a university building and was then the seat of the first Bavarian state university from 1503 to 1800. Since the size of the building was soon no longer sufficient, separate buildings were built for individual faculties, such as the anatomy faculty for the medical faculty. About fifty years before the university moved from Ingolstadt in 1800, extensive repairs had to be carried out at the high school. When the building moved away, it lost its function as a university building, but the term high school for the building remained.
Even after his university days, the building was a place of education and was primarily used as a schoolhouse. For example, it housed the Apian-Gymnasium between 1971 and 1977 until it moved to the new building on Maximilianstrasse. As early as the beginning of the 1930s, the high school was partially renovated by city building officer Franz Xaver Schwäbl[1] and the life-size fresco by painter Johannes Eppelein was created in these years.[2] A comprehensive renovation took place in the 1990s, which enabled the building to continue to be used.
