Schloss Blücherhof, Manor house in Klocksin, Germany.

Schloss Blücherhof is a neo-baroque manor house built in 1902–1904 for the Berlin zoologist Alexander Koenig, designed by architect Gustav Holland. The rendered building has a five-sided central projection on the courtyard side, reached by a driveway and outdoor staircase, with a richly decorated Jugendstil canopy topped by a dome-like hood. The entrance gate is flanked by single-storey neo-baroque buildings with wrought-iron doors in Rococo style.

The Blücherhof estate, long called Lütgenhof, passed from the von Blücher family to the von Arnims around 1791 through the marriage of Ölgrad von Blücher to Captain Hans Heinrich Ludwig von Arnim-Gerswalde. After owners including the von Hintzenstern and von Plessen families, the Berlin zoologist Alexander Koenig bought it around 1897/1898 and had the present house built by 1904 to plans by Gustav Holland. From 1951 to 1961 it served as a youth work camp, then as a special children's home until 2003.

The estate was called Lütgenhof until at least 1803, when it passed by marriage from the von Blücher family to the von Arnim family. The present name follows the older Blücher designation. The park, laid out between 1900 and 1906, holds about 200 dendrological rarities among some 120 tree species, including oaks around 600 years old.

The eight-hectare park is open to visitors and best explored on foot; the grounds lie between the manor house and the surrounding woodland. The park has been under protection since 1967, and a 1998 survey recorded more than 700 woody plants. The manor house itself is privately owned and used for exhibitions and cultural events, so access to the interior depends on the programme.

The park was laid out between 1900 and 1906 by Alexander Koenig, who had trees brought from around the world; it covers about eight hectares and holds some 200 dendrological rarities among roughly 120 tree species, including oaks about 600 years old. It was placed under protection in 1967, and a survey in 1998 recorded over 700 woody plants.
