This outstanding manor enjoys a prestigious setting above the left bank of the Rhine between Oberwinter and Remagen. Built between 1906 and 1908 as a private summer residence for an industrialist family from Cologne, it later became the official quarters of French diplomats. Architecture, history and panoramic setting combine here in a unique way.

Extensive building rights have been granted with a designated building footprint of approximately 23,000 m² in addition to the existing buildings. The development plan includes hotel, conference, spa, restaurant, additional apartments for the owners, underground parking and commercial purposes. The binding land-use plan is not time-limited. We are eager to assist with any information.

Historical Significance After World War I, the estate was used by the American occupying forces until 1919. In the 1930s, it was developed into an upscale hotel and restaurant where the Rhine society enjoyed meeting, a role it resumed after World War II following periods of military and civilian use. In the late 1940s, it became a meeting place for the film industry, hosting prominent actors.
From 1949 onwards, the manor served as the residence of the French High Commissioner and later the French ambassadors to the Federal Republic of Germany. Close to Bonn, it was a venue for diplomatic encounters and official representation.
Current Situation
Following the relocation of the German government to Berlin, the French Embassy also moved there, while the estate initially remained the property of the French Republic. In 2006, the estate was acquired by a German film producer and comprehensively restored from 2007 onward; now privately owned, the manor (which is a listed building) and its registered park are maintained in a perfect condition.
Architecture & Appearance
The first residents commissioned Ernst Eberhard von Ihne, one of the leading architects of his time and imperial court architect, to design a modern summer residence in the French style. The building features a clear rectangular layout with two short side wings, while the garden façade facing the Rhine forms the principal elevation with eleven window axes.
The west wing is distinguished by two semicircular glazed projections used as salons or winter gardens, while the east wing emphasizes horizontal articulation through a continuous projection. Built on rock and fully basemented, the house was equipped with advanced construction and technical features for its time, offering a high level of comfort.
Bright, generously proportioned rooms, near floor-to-ceiling windows, symmetrical façades, and largely original Parisian interior design continue to convey the character of a representative yet residential country estate.
Park, Garden & Outdoor Facilities
Thanks to the design by the renowned Berlin landscape architect Albert Brodersen (who conceptualised the Berlin Tiergarten), the landscape park with hydrants for irrigation from its own spring offers a balanced combination of intimacy and sweeping panoramic views. A three-tiered terraced garden links the house to the steep Rhine slope to the southeast, connecting thus the representative architecture with the unique landscape of the Rhine Valley.

The overall ensemble also includes various outbuildings:
- Coach house with 5 garages and stables (4 boxes)
- Studio house with an apartment and artist's studio – 6m ceiling height –
- Garage building with 7 single garages and a large garage
- Boiler house with a modern CO ₂ -neutral wood chip heating system and additional oil reserve heaters.
Distinguished highlights include a scenic viewing pavilion perched on the northeastern edge, while the southern grounds host an historic tennis court and a pétanque field.

Set in the vibrant Rhineland yet fully secluded, the castle offers exceptional privacy. The approx. 60,000 m² fenced estate is surrounded by oak and beech forest, with two helipads and a gatekeeper’s house ensuring maximum security.
