Burg Hemmerich, Medieval castle in Hemmerich, Germany

Burg Hemmerich is a ruined castle at Jennerstraße in the Hemmerich district of Bornheim. A red brick two-story wing with white-framed windows and a steep gray slate roof with dormers surrounds a paved courtyard. On the right, a roofless section of exposed brick and gray stone walls rises into two square tower-like remnants with small pyramidal roofs, and a low wall with stone pillars encloses the front.

The castle was built on the foundations of a Roman settlement and belonged to Knight Albero von Hemberg around 1210. Major renovations took place between 1729 and 1733, though subsequent fires later led to its reconstruction as a residential villa.

The name Hemmerich derives from the knightly family von Hemberg, first recorded in 1210. The castle became an "Öffenhaus" of the Cologne archbishop in 1392, and the hereditary title of Erbkämmerer passed with the estate through the von Aldenbrück and Velbrück families. Since spring 2023 the ruin has served as a filming location for the Sat.1/Joyn series Die Landarztpraxis.

Burg Hemmerich stands at Jennerstraße in the Hemmerich district of Bornheim. The grounds have been uninhabited since 2004 and the ruin continues to decay, so the complex is viewed from the outside only; there is no maintained park or marked trail. Since spring 2023 the site has served as a filming location for the Sat.1/Joyn series Die Landarztpraxis, so access may be restricted during shoots.

The Neo-Renaissance manor house was built after the 1906 fire, not after 1945; architect Wilhelm Graf Mörner designed it for Rudolph von Nordeck. The 1945 fire, started by dismissed forced labourers, left only a ruin. Since spring 2023 the grounds have served as a filming location for the Sat.1/Joyn series Die Landarztpraxis.
