Schloss Deutschkreutz, Renaissance castle in Deutschkreutz, Austria.

Schloss Deutschkreutz is a Renaissance castle in Austria featuring a four-wing structure with double-story courtyard arcades. Corner towers and stucco decorations characterize the exterior appearance of the building.

A medieval castle at Deutschkreutz was first mentioned in 1492 and belonged to the Kanizsay family until 1535, when it passed by marriage to the Nádasdy family. Thomas III Nádasdy had it rebuilt around 1560 as a castle in the Italian Renaissance style. The present form dates from 1625 under Paul Nádasdy, who also had the chapel built in 1632.

The painter Anton Lehmden (1929–2018) bought the castle in 1966 and restored it piece by piece; he showed his own paintings in the rooms. The building is still privately owned and serves as a museum with old furniture and tapestries on view.

The castle sits about five kilometers from the Hungarian border and offers guided tours through preserved rooms. It is advisable to check visiting times in advance.

The chapel Paul Nádasdy founded in 1632 was completely destroyed by Soviet troops who used the castle as a barracks from 1945 to 1955; its old frescoes are gone. Anton Lehmden, owner from 1966, restored the building piece by piece and showed paintings there.
