This is Schloss Haus
Source: Wikipedia ->
In the 20th century, the castle became the residence of Hereditary Prince Franz Joseph von Thurn und Taxis, who used it as a hunting lodge. After Franz Joseph married Elisabeth von Braganza in 1920, the couple lived and managed Schloss Haus as an agricultural property. In 1928 the south-west wing was increased by two storeys and the palace was completely modernized. Extensive forests with their own forestry were attached to the farm. A brewery and a distillery complemented the activities. At its peak, around 250 people lived and worked in Schloss Haus. The couple spent most of the winters in St. Emmeram Castle. On April 11, 1947, Countess D’Orsay died in Schloss Haus Theresia Grimaud.
Since the death of Franz Joseph von Thurn und Taxis in 1971, the palace complex has not been used and has stood empty. In 1986 it was entered in the list of monuments. In 2008 the Thurn und Taxis sold the castle. The new owners, the Weitzel family, carried out extensive renovations and modernizations, which were recognized in 2009 by the Regensburg district's monument protection prize.
