The graves at Harhoog are dated to the Neolithic and belonged to ancient settlements of the island's Funnelbeaker culture, probably around 3000 BC.
There were once approximately 600 of them but today only about half of them still exist.

The megalithic tombs are built with large, rough stone slabs (one or more) which are arranged in different patterns.
Harhoog dolmen is an extended dolmen, under Ernst Sprockhoff's six-category classification; the other five types are simple dolmen, great dolmen, passage grave, long barrows (without a burial chamber) and cist.

Harhhog was discovered in 1925 during excavations of earth for the construction of the Hindenburgdamm, but was only inspected archaeologically in 1936.
