It's Maes Howe. What can you say. Unbelieveable construction. You enter stooped, through a low passage, and you're inside a 5000 years old tomb.
I remember reading about it when I was a kid - I remember the Viking rune graffiti. A tour guide will take you into the tomb and show you the runes and describe the history of the tomb. I can't imagine why you, reader, haven't been there already!
Something is not right. This message is just to keep things from messing up down the road
