Burg Geretzhoven, Medieval water castle in Bergheim, Germany.

Burg Geretzhoven is a water castle in Bergheim distinguished by two round corner towers with curved roofs and a manor house set within a four-wing layout. The structure rises two to three stories and sits within its protective moat and medieval walls.

The name Geretzhoven is documented in 1328 in connection with Reinhard von Geretzhoven, while the knight's seat itself dates in its core to the 16th century. The castle originally belonged to the Cologne St. Ursula convent. In 1688 it passed by marriage to the family von Bodelschwingh-Plettenberg, who restored the buildings around 1920.

The name Geretzhoven is documented from 1328, when Reinhard von Geretzhoven appears in a charter; the castle then belonged to the Cologne St. Ursula convent. Today the restored "Miste" barn is rented out for celebrations in a historic setting, and the complex can be visited on set dates by prior arrangement.

The complex can be visited on certain dates and only after prior registration. The restored "Miste" is used for celebrations in a historic setting. The site lies in Rheidt-Hüchelhoven, part of Bergheim in the Rhein-Erft-Kreis.

The restored "Miste" barn now hosts celebrations in a historic setting, and the castle archives are kept in the Bodelschwingh collection and the Digitale Westfälische Urkunden-Datenbank. The name Geretzhoven was first documented in 1328 with Reinhard von Geretzhoven.
