Thrilled to have discovered a previously unknown "new" henge monument near Newgrange last night. Archaeologists tell me that this is a very major find. It appears to be similar in design and size to the nearby Site P, a recorded henge. Exciting times! https://t.co/Mp2pWY26Dr pic.twitter.com/CIdPSTCEJX
