Heidenwall, Medieval ring fort in Oldenburg, Germany
The Heidenwall fortress features a circular defensive structure with wooden foundations and earthen walls spanning 54 meters in diameter.
Archaeological excavations in 2007 revealed that the fortress dates back to 1032, with additional fortifications constructed around 1042 during a second building phase.
The name Heidenwall emerged when the original purpose and designation of the fortress were forgotten by subsequent generations in the region.
The fortress location near the Hunte River allowed control over an important ford connecting trade routes between Bremen and East Frisia.
The moist soil conditions preserved the wooden elements of the fortress, making it an exceptional archaeological site for studying medieval construction techniques.
