The barrow "Blocksberg" is located directly on the road near Posewald.
On the road from Lonvitz to Zirkow, north of the village Posewald, there is the megalithic grave "Blocksberg", a so-called large dolmen with a windbreak. Originally the grave had three capstones, of which only one capstone is still in almost original position - sunk into the chamber. The other two stones are in close proximity: one at the edge of the mound, the other still in the ground. The almost circular mound is still surrounded by some enclosing stones of the mound bed, whose exact shape is not known.
