Revaux (sp) Abbey?
Don’t look big enough .
I thought it might be Tintern but it’s probably bigger than Tintern
Nope, not Rievaulx or Tintern 
Glastonbury Abbey, Lady chapel maybe??
Not Glastonbury, very cold… 
You are in a rough lay bye on an un-classified road South of Barnard Castle, The ruins are Egglestone Abbey near Bowes Village.
(English Heritage property, free entry. Had to get my members handbook out to find that)
Very good Martin, that must have kept you occupied for a while lol
