Hi George,
As you know I only live about 15 minutes away from Trethevy (not Trevethy as titled) and in my opinion (without looking at the work done by others) I would guess that at some stage it has fallen and been re-erected...badly!! The fallen internal closure stone is far too tall to be either in the right place or served another purpose originally and in my opinion a couple of side uprights are also misplaced. But in fairness I have never undertaken serious research on it but strangley enough was going to do that this year.


Roy , I'm looking forward to the seeing the evidence for the orientations (and markings ), which must be based on the internal relations of the othostats and capstone as there is nothing external that is the usual stuff of archaeastronomy i.e. foresights etc . The possible number of internal relations is immense and likleihood of finding something apparently significant is consequently high . The orientations are predicated on the the structure being exactly as the builders left it .If there has been any movement or change , apart from the obvious case of the backstone then the argument for intentional alignments like that stone ,collapses .Worse , 50%of Portal Tombs have a surviving cairn and those that don't , as is the case at Trevethy have evidence of one .The surrounding cairn was the feature that at least allowed for erection of the capstone whilst supporting the orthostats .
Any surrounding cairn would diminish the number of possible plays of light except for the hole in the capstone which may not even be contemporaneous with the build , a masons view on this would be helpful i.e. to see what the tooloing may have been .
We do know about orientations of Portal tombs in relation to water courses and valleys and despite some attempts there has been nothing convincing in relation to astronomy .
Despite that it's great to see some time being spent on one monument we are sure to learn to something .
