Jagdschloss Mönchbruch, Timber-framed hunting lodge in Mörfelden-Walldorf, Germany

The Jagdschloss Mönchbruch is a hunting lodge built around 1730 by Landgrave Ernst-Ludwig of Hesse-Darmstadt at the centre of the Mönchbruch, on the north side of today's B 486 between Mörfelden and the Rüsselsheim district of Haßloch. Its plans were drawn by the Gießen master builder Colonel Helfrich Müller. The ensemble comprised six manor houses plus stables, coach houses and outbuildings; three houses were auctioned for demolition around 1850 and rebuilt elsewhere in the Groß-Gerau district.

Landgrave Ernst-Ludwig of Hesse-Darmstadt, who had introduced parforce hunting in Darmstadt in 1708, had the lodge built around 1730 to plans by Gießen master builder Helfrich Müller. Three of the six manor houses were auctioned for demolition around 1850, but Ludwig III had the complex restored in 1855 and installed a forestry office. Since 1999 privately owned, it has been under restoration, with the first section completed in December 2008.

The annual Schlossgartenfest, held until 2016, opened the ongoing restoration and planning work to the public. The middle pavilion is to become an outpost of the Mörfelden-Walldorf registry office and an ecumenical chapel, while the pavilions are converted into guesthouses linked to the neighbouring Mönchbruchmühle hotel.

The lodge stands on the north side of the B 486, roughly midway between Mörfelden and the Rüsselsheim district of Haßloch. The grounds are in private ownership and have been under restoration since 1999, with the first section finished in December 2008. The neighbouring Mönchbruchmühle runs the hotel and restaurant; the lodge pavilions are being converted into guesthouses, and the middle one is planned as a branch of the Mörfelden-Walldorf registry office with an ecumenical chapel.

Three of the six manor houses were auctioned for demolition around 1850 and rebuilt elsewhere in the Groß-Gerau district; Ludwig III had the complex restored as early as 1855 and set up an Oberförsterei there. From 1932 the Freiwilliger Arbeitsdienst, introduced under Chancellor Heinrich Brüning, was quartered in the Mönchbruch, later followed by the Reichsarbeitsdienst.
