After the Second World War, the castle served for several years as an emergency shelter for displaced persons and refugees, as well as temporary accommodation for school halls and as a retirement home. Other ways to use it in the long term failed for a long time. It was used as a dance hall, sewing and later as a riding hall.
The Markt Schwarzenfeld bought the property in 1954 with the premise "to keep the castle in the market as a landmark of our homeland and not to change its appearance". Attempts to provide the castle as an office building for the Land police or the Bavarian Red Cross were also unsuccessful. Through various foreclosures, it often changed the owner, before it was rebuilt in 1979 as a nightclub.
During the night of June 24 to June 25, 1982, the castle burned down completely, was destroyed over many years as a ruined building and had to be renovated several times to preserve the building fabric. In 1995, it was sold to a private carrier, which completely gutted it, renovated it and built the castle into a conference hotel, which opened in 1996. It is named Hotel Schloss Schwarzenfeld.
