Laudon Palace, Baroque castle in Penzing, Austria.

Laudon Palace is a Baroque water castle in Hadersdorf, in Vienna's 14th district, Penzing. Its two-storey main wing surrounds a square inner courtyard on three sides, with a single-storey service wing closing the south-east side; the ponds around it are fed by the Mauerbach stream. The cream-coloured facade has tall windows with dark shutters, dormers in the steep hipped roof and a stone balustrade along the roofline.

Field Marshal Gideon Ernst von Laudon bought the estate in 1776 and lived there until his death in 1790. It later passed to the Republic of Austria, which has used it for administrative and training purposes ever since.

The castle's name comes from Field Marshal Ernst Gideon von Laudon, who bought it in 1776 and lived here until his death in 1790. In the stair hall a Latin inscription in elegiac distichs commemorates the two nights Elisabeth Christine, wife of the future Emperor Charles VI, spent here in 1708; its capital letters read as Roman numerals give that year. Frescoes by Johann Bergl, painted around 1770, were rescued in 1954 from Schloss Donaudorf, demolished for the Ybbs-Persenbeug power station, and moved here in 1963.

The estate now serves as a training and administrative facility for the Republic of Austria and is not regularly open to the public. It is worth checking in advance when tours or events such as concerts or weddings are scheduled.

In the park stand two monumental boar sculptures that once guarded the entrance of a zoo (Tiergarten) mentioned in old literature and no longer existing. A statue shows Laudon as an ancient philosopher; it was probably first intended as a memorial for his tomb. His widow Klara instead commissioned Franz Anton Zauner's classicist tomb, finished in 1791, a cuboid with a gabled roof and relief tondi of mythological figures on all four sides.
