Haus Attenbach, Architectural heritage monument in Hennef, Germany.
Haus Attenbach is a manor house on the Sieg River in Hennef featuring two round corner towers and two stories. Its layout shows the typical arrangement of a lowland castle from the 16th century, with living spaces integrated between the defensive elements.
The property appears in monastery records from 1142, and Knight Johann von Attenbach made it his residence around 1367. The current building was constructed around 1545, replacing earlier fortifications at this strategic location along the Sieg.
The manor reflects how military design and residential comfort merged during a period when such transitions shaped local nobility. The visible round towers and their placement show how people balanced defensive needs with everyday living.
The estate is privately owned and viewable only from the outside, allowing visitors to see the towers and facade from the street. Its location along the Sieg in Hennef makes for a pleasant walk to observe the exterior architecture.
Baron Theodor von Hallberg-Broich took over the estate in 1810 and became one of the wealthiest individuals in the region within a few years. His family's influence on local history is often overlooked when visitors focus only on the building's architecture.
