Burg Bodendorf, Medieval castle in Bad Bodendorf, Germany

Burg Bodendorf is a medieval castle in Bad Bodendorf featuring a two-story manor house with seven axes, a slate-covered hipped roof, and windows framed in basalt stone. The structure combines classical castle-building features with carefully executed details at the roof and window frames.

Nicolo von Bodendorf built the castle at the start of the 13th century as a moated stronghold guarding the Aachen–Frankfurt military road alongside Burg Landskron. It stood empty and decayed from 1533 to 1608, was rebuilt, then plundered and burned in 1642 by imperial troops under General von Weerth during the Thirty Years' War. French troops raided it again in 1667, 1676 and 1692.

The castle displays water castle features with visible remnants of former moats surrounding the structure. These elements continue to shape how visitors experience and perceive the place today.

Burg Bodendorf stands in the Bad Bodendorf district of Sinzig, a lowland castle on flat ground near the Ahr. The four-winged complex with its hipped roof and cobbled courtyard is a protected monument; visitors view it from the outside and the surrounding lanes.

The castle's owners included the Cologne cathedral chapter chancellor Joseph von Groote in the mid-19th century, and from 1912 Franz Freiherr Spies von Büllesheim Maubach. In 1929 the naturopath Matthias Leisen bought it after finding a radium-bearing spring nearby, and treated his patients with the water inside the castle.
