Ale’s Stones (Ales stenar in Swedish) is a megalithic monument in Scania in southern Sweden , probably from circa 600 CE, that is, the end of the Nordic Iron Age . Scanian folklore ascribes the stones to King Ales’s grave. This site is significant for Scandinavian heritage studies.
Ale’s Stones consist of a 67 metre long stone ship formed by 59 large boulders of sandstone, weighing up to 1.8 tonnes each. (from Wikipedia).
