Ehem. Schloß ), Former castle, now monastery and disability facility, in Schönbrunn, Röhrmoos, Bavaria, Germany

Schloss Schönbrunn is a former Hofmarkschloss in Schönbrunn, part of Röhrmoos, built in 1688 by Kaspar von Schmid, with a west wing added in 1720 by Freiherr von Unertl. The complex was partly demolished in 1835 and now serves as a monastery and facility for people with disabilities. Its associated former Hofmark church Heilig Kreuz, a Baroque central building erected in 1723/24, stands nearby.

Schönbrunn was first mentioned around 800 as "Prunna"; a castle stood here by the 13th century and became a Hofmark seat in 1675. Kaspar von Schmid built the present building in 1688, and Freiherr von Unertl added a west wing in 1720. Parts were demolished in 1835. Countess Viktorine von Butler-Haimhausen bought the estate in 1862 and from 1863 it served as the "Assoziationsanstalt Schönbrunn".

The name Schönbrunn goes back to the settlement's first mention around 800 as "Prunna". Since 1863 the former Hofmarkschloss has housed the Assoziationsanstalt Schönbrunn, founded after Countess Viktorine von Butler-Haimhausen bought the estate in 1862; it served as a home for people with disabilities and a training school for young girls. The associated former Hofmark church Heilig Kreuz, a Baroque central building by Johann Baptist Gunetzrhainer built 1723/24 with advice from Joseph Effner, is now a Catholic filial church.

The building is located in Röhrmoos and can be viewed from the outside, with the surrounding area providing access. Visitors should check beforehand whether public access is available, as it may be a privately owned heritage monument.

The castle chapel, the former Hofmarkkirche Heilig Kreuz, was built in 1723/24 to plans by Johann Baptist Gunetzrhainer with advice from court architect Joseph Effner. The Baroque central building is a listed monument in its own right, separate from the castle.
