The
nave was built under architect Dietrich Landtner from 1330 to 1339 but not
consecrated until 1 November 1349. As the nearby Hofburg expanded, the Augustinerkirche gradually became engulfed by it and today is a part of the complex. Although inconspicuous from the outside, the inside is more ornate. During the reign of Emperor
Joseph II, 18 side altars were removed in 1784 when the church was restored in the
gothic style. A new side altar was added in 2004, dedicated to Emperor
Karl I of Austria (1887–1922) who is on the path to being recognized as a
saint by the Roman Catholic Church. The pulpit was designed by Hofarchitekt
Johann Ferdinand Hetzendorf von Hohenberg in 1784/85. when the church was returned to its original Gothic style. It is an early example of
Gothic Revivalism in Central Europe. The white-and-gold wooden structure is placed on a column with a foliated Gothic capital. The balustrade and the rear wall is decorated with simple blind tracery. The abat-voix forms a canopy with the usual symbol of the dove and a statue of Saint Paul (?) on the top. A painting of the interior by
Martin van Meytens from 1760 shows another simple, rectangular pulpit with the statue of the Madonna on the top.
Chapels The Loreto Chapel, to the right of the main altar, holds the silver urns containing the hearts of
Habsburg rulers, while their bodies are kept in the
Imperial Crypt.
Herzgruft contains the hearts of 54 members of the imperial family.
Cenotaph of Maria Christina Notable among the church's monuments is the memorial to
Archduchess Maria Christina of Austria sculpted by
Antonio Canova, in 1805. ==Sacred music==
