I would like to add some photos and narrative that might cast some light on the dispute, the well and coin tree are most certainly young (I believe the tree to be Victorian) but there are two graves that are certainly of Nordic Origin and are relatively old, there are also citations of this site being used by the Picts. I visited the Island this spring and found the coin tree to be dead and lying on the ground and no evidence of the well. There are crossed slabs estimated to be from the 8th century, the photos seem to tie in with diagrams I have seen in texts.
Excuse my ignorance as I am new to TMA but would this site merit being put back into an antiquity category with the well and tree being disputed?

Thanks in advance :)
