Großsteingrab Blankensee, Neolithic dolmen in Lübeck, Germany

Großsteingrab Blankensee is a megalithic burial chamber in Lübeck built from large erratic boulders arranged into a chamber formation. The structure features four supporting stones on the northern side and multiple stones on the southern side, all topped by four substantial capstones spanning about eight meters in length and three meters in width.

The grave was built between 3500 and 2800 BC by the Funnel Beaker Culture and stands as an early example of organized burial practices in northern Europe. Excavations in 1857 revealed human bones, pottery fragments, a flint axe, and a bronze knife, showing how this culture honored their dead and valued possessions.

The site is a protected archaeological monument, and its name simply ties it to the Blankensee district of Lübeck. The 1857 investigation removed the flat earth mound around the chamber, leaving the grave in a depression about 1.5 m deep. Visitors can still trace the original mound's edge from the surviving boundary stones, some partly visible.

The grave sits in a wooded area near highways B 207 and A 20 and is surrounded by a protective fence to preserve the archaeological site. It is easy to reach by car, but visitors should be prepared for a natural setting with no facilities or signage on the site.

The 1857 investigation removed the original flat earth mound around the chamber, leaving the grave in a depression about 1.5 metres deep. The same work found human bones and two pottery sherds in the chamber, plus a flint axe and a bronze knife in the mound's earth, possibly traces of later Bronze Age burials.
