Sigiburg, Archaeological ruins and castle heritage site in Hörde district, Germany.
Sigiburg is a castle ruin situated on a hill where the Ruhr and Lenne rivers meet, with partial stone walls and a tower structure called the Vincke tower still standing. The site displays remains from several fortification phases layered on top of one another.
The fortification began around 700 as a Saxon hillfort and became a strategic point during conflicts between Charlemagne's forces and Saxon defenders in the 770s. The site was later rebuilt and fortified during the medieval period with new castle structures.
The site's name reflects its role as an ancient stronghold, and visitors can see evidence of how people from different eras used this elevated location. The layered settlement history is visible in the structures and ground layout that remain today.
The site is located within Dortmund's city limits and remains accessible at any time, though the steep terrain makes it difficult for those with limited mobility. Sturdy footwear is recommended because the climb is demanding and can be slippery.
The location was a contested spot during the Saxon Wars, with archaeological finds showing that different groups fortified the same place in succession. This shifting use by Saxons, Franks, and later feudal lords makes it a layered site where past occupations remain visible in the ground.
