In Norway, beneath the Grønhaug mound, 30 metres across and 4 metres high, on the island of Karmøy, an oak ship some 15 metres long was buried. This has been known since the excavations of 1902.

In August of this year, archaeologists of the Museum of Archaeology at the University of Stavanger carried out fresh excavations and reached the ancient ground surface, where they found a man-made stone cairn, covered with layers of soil and turf, with a ring of stones at its base, presumably of the Bronze Age.

That is to say, the ship burial of the ninth century was made on top of a mound that was already more than a thousand years old
