At Wulfener Berg was an important stone age grave field with megalithic tombs from the period 3600 - 3200 BC. Particularly noteworthy were several "long beds" of up to 130 m in length (giant beds). In 1836, the antiquarian and pastor Diederich Harries described the already largely destroyed graves at Wulfen. The stones were blown up by stonecutter and sold as building material. Today, there are no traces left of the burial ground. The association "Beautiful Wulfen" inspired the replica of a long bed and made 2010 for the implementation of the project. The model was inspired by a drawing made by Pastor Harries from a long bed that was still in good condition at the time, which lay on the salt meadow below the Wulfener Berg.
The long bed consisted of an east-west directed stone frame and two chambers, each with seven support stones and two capstones. This grave was destroyed in 1876, when stones were needed for dike construction. The stones used for the 60 m long and 7 m wide replicas come from different parts of Fehmarn. In the middle of the tomb one set a "sacrificial stone". The two smaller stones in front of the entrances of the burial chamber are called "guards". The overriding with earth, which was customary in the Stone Age, was abandoned, as well as the closing of the gaps between the stones with dry masonry and clay.
By bike you can easily reach the reconstruction via the public accessible path through the golf course or from the center of Wulfens.
