Amlishagen Castle, Medieval castle in Amlishagen, Germany

Amlishagen Castle is a spur castle above the Brettach valley near Gerabronn in Baden-Württemberg. Its 20-metre-high, 19-metre-long and 2.5-metre-thick shield wall on the hill side, fronted by a neck ditch, defended the only weak point; a reconstructed wall walk reached by a spiral staircase tops it.

The site was first recorded in written sources in 1253 and underwent major expansions during the 14th century. Further modifications in 1601 and the 19th century shaped its appearance and function.

The castle's name comes from the village of Amlishagen and the Lords of Amlishagen, who held it in the 13th century. After the Wollmershausen family died out around 1700, the estate passed through several owners until Blücher's personal physician Johann Karl von Horlacher bought it in 1821; his descendants still live in the castle and the adjoining Schloss Amlishagen.

The grounds are open on weekends from Easter through October 31, though the interior is not available for visitors since it remains privately occupied. Check ahead for current opening details, as access may vary.

The castle was bought in 1821 by Johann Karl von Horlacher, Blücher's personal physician, not by Blücher himself. A distant descendant of Horlacher still owns the castle and lives there.
