Hello Lutalica_1974,
I am not sure about this POI. Could you give the source of this entry? Müller/Reimers described this dolmen as destroyed in 1893, Sprockhoff could not find any remains as early as in the 1920s, there is no mention in the Denkmalatlas Niedersachsen, and there is nothing to see on any aerial image.
