Schloss Lindenau, Renaissance castle in Lindenau, Germany

Schloss Lindenau is a two-story Renaissance castle in Lindenau, consisting of a block-like rectangular main building with a tower added in 1609 and a round tower with a conical roof on the north side. The south side retains remains of an earlier Gothic structure, and two neo-Baroque side wings added in 1920 and 1923/24 give it the appearance of a three-winged Baroque complex around a cour d'honneur.

The castle was built in 1584 as a fortified residence and received a tower addition in 1609 during a period of regional unrest. Later owners added Baroque details and redesigned parts of the property, leaving traces of each era on the building.

The estate was run by a Fürstlich zu Lynar, Gräflich von Redern'sche Güterverwaltung rather than by the owners themselves. From 1953 to 1998 the castle housed the children's home "Paul Paulick", named after a local figure. Public viewing appointments are held at irregular intervals.

The castle has stood empty since being gutted after 1998, and the municipality has been seeking an investor since regaining ownership on 14 November 2018. Public viewing appointments are held at irregular intervals. Outside those dates the building and its island setting can only be seen from the surrounding paths.

The park around the castle was laid out in 1736 as a formal Baroque garden and later redesigned as an English landscape park in the 19th century. This kind of transformation was common across German estates at the time, as owners moved away from geometric order toward a more natural-looking setting.
