History+
The hamlet where the castle is located was originally named Lindenbronn and came into the possession of the House of Hohenlohe-Langenburg in 1556. From 1736, Count Ludwig zu Hohenlohe-Langenburg commissioned the construction of a summer residence. The plans for this came from Leopold Retty, who drew inspiration from early 18th-century Parisian urban architecture, although the design was implemented in a simplified manner. Completed in 1743, the hunting lodge included, in addition to a few utility rooms, a garden and dining hall on the ground floor, a larger hall on the upper floor, and three living apartments. It embodied the type of a Maison de Plaisance.
