The Great Sacred Monuments of Stenness

Details of the putative avenues between the Stones of Stenness and the Ring of Brodgar (from the resarch agenda) ; Watch Stone, Lochview, Stone of Odin, Comet Stone. Also suggested the pairs of stones (indicated at sockets alongside) at the Watch Stone and the Stone of Odin as symbolic doorways linking the circles.
Against the first of these the possibility that the Watch Stone and its companion socket are fragments of a circle now under the loch waters. Contra the second that they actually found three sockets from the Stone of Odin location, the third a few metres away.
