A first chapel was built by order of Charlemagne in the place where, according to tradition, the Roman temple dedicated to Juno was built. The chapel which was built after the fall of the Roman Empire of the West seems to have been the oldest in Bavaria and this earned it the nickname "Alte Kappelle", the «Old Chapel».
In 1964, at the suggestion of Bishop Rudolf Graber, the Collegiate Church of Our Lady of the Old Chapel was elevated to a smaller basilica by Pope Paul VI.
