Schloss Jaidhof, Castle in Jaidhof, Austria

Schloss Jaidhof is a castle in the centre of Jaidhof in the Waldviertel, Lower Austria. Its plan is a Baroque three-storey courtyard building, with two storeys on the courtyard side, and a core from the second half of the 17th century. The facade has classical pilaster strips and window frames from around 1800, reworked in the Historicist style in the second half of the 19th century. The main wing has triangular gables and neo-classical columned balconies with balustrades, above which rises a three-tiered tower with a small onion dome. An English garden with ponds and the remains of a pavilion extends east of the castle.

The castle appears in records as early as 1381 and passed through many hands over the following centuries. Georg Ludwig von Sinzendorf bought it in 1662 and reshaped it into a noble residence, giving the property much of the character it still shows today.

Schloss Jaidhof is the headquarters of the Priestly Fraternity of St. Pius X for all states of the former Habsburg monarchy, including Austria, South Tyrol, the Czech Republic, Slovakia, Hungary, Slovenia and Croatia. The building also hosts seminars, retreat courses and youth work. The estate's lands, however, remained in the hands of the Gutmann family after Rosa Gutmann bequeathed the castle to the fraternity in 2003.

The castle is the headquarters of the Priestly Society of St. Pius X and is not a public museum, so there are no regular visiting hours or guided tours. It stands directly in the centre of Jaidhof village in the Krems district of the Waldviertel. The English garden with its ponds and pavilion remains lies east of the building.

Between 1938 and 1945 the castle was used as a barracks and training facility, after which the Gutmann family had to buy it back once the war ended. This episode is rarely mentioned but shows how closely the building's fate was tied to the events of the 20th century.
