The site of ‘de fem dårlige jomfruer’ (the five bad virgins) is located at the foot of Karmsund bridge just outside Haugesund, Norway.
The site dates back to the iron age to approximately 300 BC. It combines the symbols of the yoni and phallus, with three standing stones forming a trident shape (treudd), which is quite unusual in Norway, plus two standing stones in the middle.
They stand on top of a grave, which contained an urn, and is of German origin (southwest Rhine region - I wonder if from the Freiburg area as the local Badisch dialect is pretty similar to west coast Norwegian?). Inside the urn were the ashes of the deceased, wrapped in a bear skin - suggesting a ritualistic ceremony.
The legend of the five virgins says that they stood at the site and tried to seduce King Olaf, who was on his way to Avaldsnes (you can actually see the Olaf church from the standing stones site), to come over and see them. Instead he chastised them for their shamelessness and turned them into stone.
