Jagdschloss Grünau, Renaissance hunting castle in Neuburg an der Donau, Germany.

Jagdschloss Grünau is a whitewashed Renaissance hunting castle with a steep reddish-brown tiled roof, standing on a grassy slope in the floodplain forest about seven kilometres east of Neuburg an der Donau. A tall gabled block with an arched entrance and red-shuttered windows forms the core, the Altes Schloss built 1530/31; a slender pointed turret marks the angle where a long, lower wing extends to the right. Behind the roofline rises a white tower with a patterned gable.

Ottheinrich, Count Palatine of the Wittelsbach dynasty, had the lodge built for his wife Susanna of Bavaria from 1530. The tower-like core, the Altes Schloss, went up in 1530/31; wings around a large courtyard followed in 1537/39, and work finished in 1555. Originally a moated castle, its ditches have since silted up.

The core building preserves its 16th-century room layout: a Tafelstube, two princely apartments with living rooms, sleeping chambers and a shared studiolo, plus rooms under the roof. Wall paintings begun by Jörg Breu the Younger survive there. Since 2005 the castle has hosted garden days in May and a Christmas market in December.

The castle stands about seven kilometres east of Neuburg an der Donau, in the largest contiguous floodplain forest of Central Europe. The moats of the original water castle have silted up, so no water surrounds the buildings today. Concerts and, since 2005, garden days in May and a Christmas market in December are held here; the Auenzentrum Neuburg opened on 19 April 2008.

The moat that once ringed the castle has silted up, so no water channels remain visible today. What survives is the original residential tower core of 1530/31, whose room layout and wall paintings begun by Jörg Breu the Younger still show how a princely hunting residence was divided.
