Hünenburg Baden

The place Baden is first mentioned in Adam of Bremen's Hamburg Church History, probably for the year 1013. Adam reports that the Archbishop of Bremen Unwan gave the "curtis Botegun" to the Bremen Cathedral Chapter. The Hünenburg itself is never mentioned in historical tradition. The archaeologist Hans-Wilhelm Heine assumed a dating to the 11th century due to the shape of the castle as a mighty earthen rampart with a small interior. Since the Archdiocese of Bremen had possessions in Baden, he assumes Archbishop Adalbert as the builder. The latter pursued a systematic castle building policy between 1063 and 1066 and could have been interested in securing this strategic point. Since no archaeological investigations have taken place so far, there is also no knowledge from this side about the dating and duration of the castle's occupation. It is historically documented that Swedish soldiers entrenched themselves on the Hünenburg during the Thirty Years' War.

The Hünenburg is located on the northern steep bank of the Weser and has a semi-oval rampart over 25 m wide and still preserved height of 4.5 m. This protected the castle on three sides, while in the south the steep slope served as natural protection. In front of the rampart is a 14 to 15 m wide and 2.5 m deep ditch. Striking is the small area of the interior of approx. 35 × 80 m in relation to the fortification. The access is presumed at the western end of the rampart, where there is a larger gap between the rampart and the edge of the slope. A pre-rampart may have existed in the north, which was still recognizable at the end of the 19th century and in 1938.
