Schloss Achau, Medieval water castle in Achau, Austria

Schloss Achau is a three-storey, four-winged water castle in the centre of Achau, enclosed by a moat and hidden from the street by its park. The wings surround a rectangular courtyard, and the south-east corner tower is large enough to be seen from a distance. Above the entrance portal is the stone coat of arms of the barons von Moser.

The first mention of this structure dates to the 12th century, when it had a simpler form. In 1650, it underwent major rebuilding under Bishop Ulrich Grappler von Trappenburg of Passau, taking on the shape we see today.

The structure shows building elements from different periods, with medieval walls standing alongside alterations from the 17th and 19th centuries. Visitors can observe these layers when entering the courtyard and examining the varying styles of each wing.

The castle sits in the center of the village and is visible from outside, but entering requires care as large sections need renovation. Access to the interior may be limited, so it is advisable to check ahead what is available for visitors.

The stone coat of arms of the von Moser barons, who acquired the castle in 1732, is set above the entrance portal. The southeast corner tower is large enough to be seen from a distance, even though the building itself is hidden from the street by the surrounding park.
