Ebreichsdorf Castle, Medieval castle in Ebreichsdorf, Austria

Ebreichsdorf Castle is a three-storey water castle on a bastioned pentagon in a pond at the western edge of Ebreichsdorf, Lower Austria. Its nearly square plan (31 × 34 m) encloses a courtyard with arcades on the north side, and a three-arched stone bridge forms the entrance. Two towers of 27 and 34 m rise above the steep hipped roof; a free-standing Gothic chapel stands on the south terrace.

Ebreichsdorf Castle was first documented in 1294, when a Heiligenkreuz charter named Otachar von Ebreichsdorf; it belonged to a chain of fortifications with Ebenfurth and Pottendorf guarding the Vienna Basin. In 1474 it resisted the advancing Hungarians but soon fell to Matthias Corvinus, whose garrison stayed until the Peace of Pressburg in 1491. Turkish raiders overran it in 1529, and in 1568 Hieronymus Beck von Leopoldsdorf rebuilt the old stronghold as a Renaissance palace with three towers.

The castle is a private residence of the Drasche-Wartinberg family and cannot be visited inside. Its image was used by the German toy company Ravensburger for a jigsaw puzzle, which spread the view of the water castle and its park beyond Austria.

The castle is a private residence of the Drasche-Wartinberg family and cannot be visited inside. The surrounding English park is enclosed by a long wall; the town-side entrance is an early-classicist portal with an iron grille, pillars with vases and putti playing with dogs. A golf course and a polo ground occupy part of the park.

Archaeological finds near the castle include a decorated golden drinking vessel from the Bronze Age, similar to artifacts found in the Baltic region. Such discoveries suggest the area was inhabited long before the medieval period.
