Schwalenburg, Medieval archaeological site and castle in Schwalefeld, Germany

Schwalenburg is a medieval castle and archaeological site in Schwalefeld situated on elevated ground. The structure displays typical features of defensive fortifications from that period and offers insight into construction methods of the era.

The early medieval hillfort with three concentric ramparts was probably built between the late 8th and 10th centuries, in Carolingian or Ottonian times. The oldest part is the middle ring, enclosing two hectares; the inner ring measures 75 to 90 m across. The site was first documented in 1537 as the "Borgh zu Schwalefeld", already wooded by then. Excavations took place in the early 20th century.

The fortress shows traces of medieval defensive structures that visitors can still observe today. It reflects how local communities built and protected their strongholds during that era.

Visits require advance arrangements since the site has limited access and is protected. It is advisable to contact the location before visiting and wear appropriate clothing for the terrain depending on weather conditions.

The rampart was first recorded in a 1537 land register as the "Borgh zu Schwalefeld", and by then it was already overgrown with trees. Excavations followed in the early 20th century, and since 2009 an 8.5 m wooden viewing tower has given an overview of the three rings.
