Burg Innhausen

Burg Innhausen is a castle ruin in Wilhelmshaven that now appears as elevated ground where the original structure once stood. The site covers an area of about 140 by 120 meters and rises slightly above the surrounding landscape.

The fortress was founded around 1350 by Ino Tjarksena, a judge of Östringen, and remained a regional power center until its demolition in 1531. After its abandonment, a mill operated on the site until 1626, before the grounds were leveled around 1850.

The fortress served as the seat of the Innhausen and Knyphausen family, an influential East Frisian ruling dynasty. Today only the elevated terrain and historical records remind visitors of its former importance to the region.

The site has no visible building remains today and consists of slightly elevated ground. Visitors will find few physical traces here since stones from the original fortress were reused for construction elsewhere.

After the fortress was demolished in the 16th century, its name was later transferred to a nearby farmstead that still exists today. This shows how the name of the former seat of power found a second life in the local landscape.
