Rammenau (German name; Upper Sorbian name: Ramnow, pronounced [ˈʁamnɔf]) is a municipality in the district of Bautzen, in Saxony, Germany.

It is known as the birthplace of the well-known German philosopher Johann Gottlieb Fichte (1762–1814).

[3] Rammenau Castle was built between 1721 and 1735 by architect Johann Christoph Knöffel for Ernst Ferdinand von Knoch, chamberlain of king Augustus II the Strong.

As Knoch went bankrupt with the immense costs of this project, Franz Josef von Hoffmann purchased it in a foreclosure auction in 1744.

Today it is owned by the State Palaces, Castles and Gardens of Saxony and open to the public, housing a museum with period furniture.
