Rennhof, Late Neoclassical château in Hüttenfeld, Lampertheim, Germany.

Rennhof is an Empire-style château built by Baron Mayer Carl von Rothschild by the end of 1853 in Hüttenfeld. A tower with a battlemented viewing platform rises above the three-storey central block, and a two-storey south wing holds the hall, followed by a three-storey section with an iron-columned veranda on the first floor. A landscape garden lies behind it.

Baron Mayer Carl von Rothschild built the manor in 1853 as a prestigious residence. Ownership changed several times later, with the Löwenstein-Wertheim-Freudenberg family acquiring it in 1889.

Since 1954 the castle has housed the Lithuanian Gymnasium Hüttenfeld, and it is also the central office of Lithuanians in Germany. A Lithuanian flag often flies from a mast at the centre of the tower's battlemented viewing platform. The school's modern buildings stand to the north of the castle.

The manor is located at Lorscher Str. 1 in Lampertheim and available for events such as conferences and celebrations. Visitors should check in advance about current availability since the building is also reserved for private functions.

The tower's square shaft turns polygonal above the roof and ends in a crenellated viewing platform; a mast at its centre often flies the Lithuanian flag, a detail easily missed from the street.
