The church shows an impressive interplay of Baroque as an expression of joyful faith and Classicism as an expression of reason. Between the strict lines of Classicism, lush stucco work and putti appear. Ceiling paintings tell of the life and death of St. Ignatius. They were originally created by the Baroque painter Johann Baptist Enderle but have been restored multiple times.
Highly notable is the Classicist organ case (1774-81) above the main entrance, the organ itself dates from 1837.
Under the church is a crypt, where along with clergy and parishioners, the master builder, the stucco worker, and the carpenter of the church rest. The towerless church is surrounded by a parish garden, where the large crucifixion group, the tomb of the sculptor Hans Backoffen (died 1519), and a Gothic wooden crucifix can be seen.
