The thirty-meter bed of the Funnelbeaker culture

The Großsteingrab Probsteierhagen is a megalithic tomb from the Neolithic Funnelbeaker culture located south-southeast of Probsteierhagen in the district of Plön, Schleswig-Holstein.

The tomb consists of an east-west oriented Hünenbett, which is a passage grave. The bed stretches 30 m long and 7 m wide. Some stones from the surrounding enclosure are still present, though a large stone at the eastern end of the bed appears to have been moved in recent times.

At the eastern end of the bed, the remains of a northeast-southwest oriented burial chamber are visible in a pit. Due to the small size of the pit, the chamber is believed to have been an extended dolmen. In a 1959 photograph by Ernst Sprockhoff, the northeastern end stone and two adjacent wall stones of the southeastern side were still intact. One of the wall stones from the 1959 documentation is now missing.
