Wiener Neustadt is a city located south of Vienna, in the state of Lower Austria, in north-east Austria. It is a self-governed city and the seat of the district administration of Wiener Neustadt-Land. The city is the site of one of the world's oldest military academies, the Theresian Military Academy, which was established by Empress Maria Theresa of Austria in 1752 to train officers for the Austrian army.

In the late 15th century 12 statues of the Apostles were added in the apse, while the bust of Cardinal Melchior Klesl is attributed to Gian Lorenzo Bernini.
