Bumannsburg

Bumannsburg is a medieval castle site near Rünthe in Bergkamen with remains consisting of a rectangular central stronghold and a large outer defensive area. The layout shows the typical structure of an early medieval fortress with fortifications that are still identifiable at various points.

The fortress was built between 772 and 802 AD, during the time when Charlemagne defeated the Saxons and brought Central Europe under his control. Archaeological excavations in the 20th century revealed finds showing how long this place remained occupied and in use.

The name likely refers to a leader or owner from the early medieval period whose memory was preserved in the place name. Walking across the site today, one can sense how this location once served as a stronghold and display of authority.

The site is freely accessible and can be viewed from outside, with some earthworks and ditches still clearly visible. The city of Bergkamen provides information and guidance for visitors who want to learn more about the excavations and discoveries.

Pollen studies from 2006 revealed how the landscape vegetation changed through three distinct phases over a thousand years. These botanical traces are invisible today but reveal how much the area surrounding the fortress transformed over time.
