Rosenburg, Romanesque Revival villa in Kessenich district, Bonn, Germany.

Rosenburg is a Romanesque Revival villa in the Kessenich district of Bonn with multiple wings and corner towers at each end of the structure. The building connects two separate sections through a central tower and now functions as residential apartments.

Georg August Goldfuß, a palaeontologist and zoologist at the University of Bonn, had the country estate built in 1831 to a design by architect Carl Alexander Heideloff. In 1862 the Düsseldorf silk manufacturer Gustav Schlieper bought it with six hectares of woodland for 8,000 thalers. From 1950 the Federal Ministry of Justice occupied it, followed in 1973 by the Bundeswehr's Armed Forces Office; the last staff left in early 2006.

The name Rosenburg is not explained in the sources; what visitors can see today is a former government seat turned condominium complex. The 1831 villa, built for palaeontologist Georg August Goldfuß, was converted around 2010 into owner-occupied flats, so the building is encountered as a gated residential address rather than a public monument.

The Rosenburg stands in Kessenich, Bonn, and has been used only as a residential complex since its conversion was largely completed in 2010. The grounds are private, so the villa is seen from the public street; the three wings and corner towers are best viewed from outside the property line.

The property originally included six hectares of woodland that were purchased along with the building by Gustav Schlieper in 1862. This generous landscape still influences the character of the setting within the urban area.
