DSCF3861 On the Gripsholm castle grounds there is this upright, flat rock with a snake coiled into a spiral, and the whole length of the snake is inscribed with what looks like runes. I’m sure there was an explanation next to it, and I conveniently didn’t pay attention to it. So now I don’t know what this is.
