Imagine my even greater delight when I realised that I have actually been within 600 yards of Grutness. In March 1985, some archaeological colleagues and I paid a very wet visit to the nearby ancient settlement of Jarlshof.
Apparently, the name Grutness is from the Old Scandanavian grjót nes, meaning gravel promontory.
So, there you have it: Gruts means gravels.
What does Grutness mean to you chaps?
