[1] It was remodelled in 1724–30 by Johann Georg Ettenhofer [de] (vaults, renovation of pillars); in the interior are Rococo frescoes and stucco ornament by the Asam brothers.

After the demolition of the hospice buildings in 1885, Franz Lšwel added three bays at the west end of the church and gave it a Neo-Baroque facade.

In the late 1960s, architect Erwin Schleich replaced the church's simple white interiors from the 1950s renovation with recreations of its original frescoes and Rococo ornamentation.

[2] Of the original Gothic church, only the choir buttresses and the north wall of the nave remain.

Among several items of art-historical interest in the church are: in the portico, to left and right of the main entrance, parts of a bronze memorial made in 1608 by Hans Krumpper for Duke Ferdinand of Bavaria, Infante of Spain; in the chancel, the high altar by Nikolaus Stuber (1730), with an altarpiece by Ulrich Loth depicting The Effusion of the Holy Ghost (1661) and two flanking figures of angels by Johann Georg Greiff (1729); in the right aisle, a series of wall paintings (1725) by Peter Jacob Horemans illustrating the Seven Gifts of the Holy Spirit; in the Kreuzkapelle, a late Gothic crucifix (1510); and, midway along the left aisle, an altar with an allegedly miraculous image of the Hammerthaler Madonna (15th century).
