The church was constructed between 1763 and 1774 to the plans of Johann Peter Jäger, namely in place of the old church of a suburb enclosed within the city wall after 1200.
The church shows an impressive interplay of baroque, as the expression of joy in faith, and classicism, as the expression of reason. Luxuriant stucco works and puttos appear between the strict lines of classicism. Ceiling frescos relate the life and death of St. Ignatius. They were originally by the baroque painter Johann Baptist Enderle, but were later touched up several times.
