Schloss Allner, Medieval château in Hennef, Germany.
The four-story mansion displays a cross-shaped layout with rectangular towers at the front corners and a central lantern roof from the mid-17th century.
Built around 1400 as a water castle by Arnold von Merkelsbach, the structure underwent transformations from defensive fortress to residential château over several centuries.
The castle's Gothic revival design elements and stone engravings represent the architectural preferences of German nobility during different historical periods.
Located on the southern slope of Nutscheid Ridge overlooking the Sieg River, the castle now contains private condominiums and remains closed to public access.
During World War II, German forces used the castle as a defensive position against the US 97th Infantry Division, resulting in substantial damage to its southern tower.
