Mitterau Castle, Protected castle in Markersdorf-Haindorf, Austria.

Mitterau Castle is a substantial stone structure in Markersdorf-Haindorf that shows the architectural style of noble residences from the 1600s. The building features solid stone walls and design elements typical of Austrian stately homes from that period.

Built around 1600, Mitterau Castle was given its present form in 1754. Since 1710 it has belonged to the Montecuccoli family, and around 1740 Count Zeno Montecuccoli moved the seat of the estate here from nearby Hohenegg Castle. The building was severely damaged in the Second World War.

The Montecuccoli family has held the castle since 1710, and Count Zeno Montecuccoli moved his seat of power here from nearby Burg Hohenegg around 1740. The estate is still run by Albert and Felix Montecuccoli, who manage 950 hectares of forest.

The castle stands in Mitterau, part of the market town of Markersdorf-Haindorf in Lower Austria, and is a listed building. The 950-hectare forest estate around it is privately managed by Albert and Felix Montecuccoli, so the grounds are not public walking country; view the building from the public approach in the village.

The estate covers 950 hectares of forest, managed today by Albert and Felix Montecuccoli. The family has held the castle since 1710, when it passed to the Montecuccoli noble line, and Count Zeno Montecuccoli moved his seat here from nearby Burg Hohenegg around 1740.
