Daun-Kaserne, Military training school in Wiener Neustadt, Austria

Daun-Kaserne is a three-storey complex built 1939–1940 in the Akademiepark south of Wiener Neustadt's castle, with two courtyards to the north and an open honour courtyard to the south. Its facade toward the Burgplatz has an entrance risalit with round arches, stone-framed windows, and a foyer and ballroom with monumental stone columns. Since the 2022–2023 renovation it houses the Bundeshandelsakademie für Führung und Sicherheit, with 10 classrooms, 5 media and project rooms, 3 computer rooms, 8 study rooms, a science lecture hall, a business centre and 46 rooms with 142 beds.

The German Wehrmacht built the complex between 1939 and 1940 as a course building in the Akademiepark, on the site of a swimming pool. Damaged in the war, it was repaired in 1948–1949 and housed municipal schools from 1950. The Austrian Army moved in on 14 September 1956 with Feldjägerbataillon 1 from Graz, and on 20 December 1966 it was named after Field Marshal Leopold Joseph von Daun.

The building was named in 1966 after Field Marshal Leopold Joseph Graf Daun, an influential 18th-century Austrian military commander. This naming reflects the long tradition of military education connected to this location.

The grounds are located in Akademiepark with clear signage making navigation straightforward, as modern markers identify the main areas. Visitors should keep in mind this is an active school facility, so arranged visits are advisable.

The building stands on the site of a former swimming pool, so the Wehrmacht's 1939–1940 course building replaced a bathing area. Since July 2022 the complex has been gutted almost to its shell and rebuilt for the Bundeshandelsakademie für Führung und Sicherheit, which moved in after the renovation was handed over on 27 June 2024.
