Hofmannsthal-Schlössl, Manor house in Rodaun, Austria

The Hofmannsthal-Schlössl is a two-story manor house with additions arranged around a rectangular courtyard, all enclosed by a boundary wall. The connected buildings create a unified residential complex that reflects the comfort and style of an affluent household from earlier centuries.

The estate appears in the Rodaun land register kept since 1692. A 1724 construction date for Prince Trautson is unconfirmed. Carolina von Trautson owned the house from 1755 to 1765. In 2016 Katja Kaluga and Katharina J. Schneider traced the Maria Theresia and Countess Fuchs stories to writer Maria Grengg, a resident from 1942.

Hugo von Hofmannsthal rented the Schlössl in 1901, shortly after his marriage, and lived there mainly in the warm months until his death in 1929; the house could only be heated with wood stoves. His wife Gerty stayed until she fled to England after the 1938 Anschluss. The building is privately owned and not open to visitors.

The house is privately owned and not open to visitors; the courtyard, garden and interiors cannot be toured. It stands at Ketzergasse 471 in Rodaun, reachable by public transport within Vienna's 23rd district. Central heating was installed only after 1963, and the house was restored again in 1988. Until then it was heated solely with wood stoves.

The house is privately owned and cannot be visited inside. Its name is misleading in another way: research published in 2016 by Katja Kaluga and Katharina J. Schneider showed that the stories linking it to Maria Theresa and Countess Fuchs were invented, largely by writer Maria Grengg, who lived there from 1942 until 1963.
