These two megaliths are on a photograph in David Trump's book "Malta: Prehistory and Temples" and described as possible site of a temple. So if it's a mistake, it looks like it is in the publication I have mentioned, unless I have misidentified the site (but on Trump's photograph there were definitely no trees, I'm quite convinced these are the same stones). Currently I do not have access to the book, I will double check it as soon as I can. I am aware of another temple site in the nearby, that is why I gave this one number 2.
Something is not right. This message is just to keep things from messing up down the road
