Hagen Settlement: Tunnel Valley and History

In the wider region surrounding Hagen Settlement, nature conservation, Ice Age landscape history and archaeological traces converge. The Tunnel Valley is entirely protected as a nature reserve and consists of two adjacent areas: the 202-hectare Stellmoorer Tunnel Valley in Hamburg and the 339-hectare Stellmoor-Ahrensburg Tunnel Valley in Schleswig-Holstein. The two protected areas are in different federal states and border one another—a specific regional contrast that makes it easier to understand the Tunnel Valley’s setting.

Ice Age Landscape and Diverse Habitats

The Tunnel Valley formed about 15,000 years ago, towards the end of the last Ice Age. Meltwater made its way beneath the ice and shaped the valley. Today, the landscape includes dry grassland, coppice woodland (low forest) and wetland habitats, which provide an important refuge for endangered plants and animals. These terms refer to different habitat types and show that the landscape cannot be reduced to a single type of natural setting. Together with the adjacent Höltigbaum Nature Reserve, the Tunnel Valley forms a natural unit. Its geological formation explains the valley’s origins; its varied habitats offer a second, ecological perspective.

From Prehistoric Sites to Arnesvelde

The Tunnel Valley is known for its unique concentration of prehistoric sites from the Upper Palaeolithic. The remains of the medieval Arnesvelde Castle in the northwestern part of Hagen Forest mark a different period; the castle stood until 1594. Two distinct historical points of reference thus sit side by side: the prehistoric sites and the castle, which survived into the late 16th century. The castle’s end in 1594 gives this medieval point of reference a specific date. When planning your trip, you can distinguish between these topics by period: the sites offer a glimpse into prehistory, while Arnesvelde takes you into medieval history.

Putting a Planned Cycling Link into Context

Ahrensburg’s 2012 transport plan proposes an additional cycling link from Hagen Settlement via U-Ost and the Ahrensfelder Weg cycle street to the town centre. This is a proposal in the plan. If this link is important for your travel plans, check its current status before your trip. The planned cycling link is a different kind of topic from the nature and history highlights: it focuses on the connection between the settlement and the town centre.

Weighing the Topics When Looking for Accommodation

When looking for a holiday apartment in Hagen Settlement, it helps to treat the regional topics as separate criteria for making your choice. Nature lovers may be drawn to the Tunnel Valley, its habitats and its history of formation; those interested in history may focus more on the Upper Palaeolithic sites or Arnesvelde. The cycling link belongs in a different category: it is a transport topic from the 2012 plan and should be checked for the latest information if it is important to your decision.
