Kollmitz Castle is a ruined castle east of Raabs an der Thaya in Lower Austria. The castle was first mentioned in the 13th century and the construction of its main tower was completed in 1319.
In the 14th century the castle was used as a district court with ownership changing often. In 1411 the Freiherr von Hofkirchen came into possession of the castle, whose family would control the castle for the next two centuries. The Hofkirchen family lost possession of the castle in 1611 when Wolfgang von Hofkirchen died in exile in Prague during the Habsburg’s Counter Reformation, which saw him as a ringleader of Protestant nobility.
Following the end of Hofkirchen control, the castle changed hands several times and may even have been abandoned. In 1708 the Castle was acquired by Franz Anton von Quarient und Raal under whom the castle fell into disrepair as it no longer could serve any practical purpose.

The imposingly grown complex originated in 1120 as a motte, a small hilltop tower castle. After numerous changes of ownership, the castle was extended onto two islands, but it was not until the 14th century that it underwent significant alterations and extensions under the von Oer family. The estate experienced its heyday in the middle of the 18th century, when it covered an area of almost one square kilometre and consisted of five further outer castles in addition to the core castle, which were secured by ramparts and moats.
The well-maintained condition of the castle today is thanks to the late Wilfried Grewing, the former lord of the castle. The foundation named after him has been particularly committed to preserving the property since 2020.
