The church impresses with its combination of Baroque, which expresses the joy of faith, and Classicism, which stands for reason and clear lines. Between the strict classicist forms, opulent stucco work and putti stand out. The ceiling paintings, which tell the story of the life and death of St. Ignatius, originally come from the Baroque painter Johann Baptist Enderle and have been revised multiple times since.
Particularly worth seeing is the Classicist organ case above the main entrance (1774–1781), while the organ itself dates back to 1837.
Below the church is a crypt where, alongside clergy and parish members, the master builder, the stucco worker, and the carpenter of the church have found their final resting place. The towerless church is surrounded by a parish garden, where the large crucifixion group, the tomb of the sculptor Hans Backoffen († 1519), and a Gothic wooden crucifix can be seen.
