Mühlenbach Castle

Mühlenbach Castle is a vanished lowland castle in Koblenz. Of the castle, built around 1300 in what is now the Arenberg district and destroyed in the 17th century, only the main tower remains.

Mühlenbach Castle was built around 1300 by Hermann II von Helfenstein as a moated castle in the headwaters of the Mühlenbach stream. In addition to their ancestral castle (Helfenstein Castle), which was located below the Electoral Trier Ehrenbreitstein Castle, the Helfenstein family also owned Sporkenburg Castle near Eitelborn. They gave their name to the imperial lordship, which included the villages of Arenberg and Immendorf, as well as several mills on the Mühlenbach.

In the 14th century, Mühlenbach Castle became a Ganerbenburg (jointly inherited castle), belonging to the Helfenstein and Brandenburg families. The Brandenburgers sold their share in 1445 for 2000 guilders to Johann von Helfenstein. After the Helfenstein family died out, the castle passed to the von Rolshausen family in 1580. In 1626, it finally came into the possession of the von Wrede and von Stein-Kallenfels families.

During the Thirty Years' War, Mühlenbach Castle was destroyed, but then rebuilt. The final destruction of the castle complex occurred in 1692 by the French during the War of the Palatine Succession. Only the main tower remained, which was used as a granary in the early 20th century.
