The Blue Stones

Roger Mercer noted that the blue stones are finely worked exceptionally. He suggested that they were brought by an older date not yet specified localized Monument here in Pembrokeshire. Most other archaeologists agree, however, that the blue stones were processed compared with the Sarsensteinen. If Mercer's theory is correct, the blue stones here might have been introduced in order to confirm an alliance or display superiority over a defeated enemy. Constellations of blue oval stones, which are similar to Stonehenge 3 IV, were also found in the known places as Bedd Arthur in the Preseli mountains and on the island of Skomer off the southwest coast of Pembrokeshire. Some archaeologists have proposed a very speculative interpretation that the igneous and sedimentary rocks of the Blue Sarsensteine are symbolic of an alliance between two cultures from different landscapes and, consequently, with different backgrounds.

New analysis of the contemporary tombs in the area, known as the Boscombe Bowmen, have shown that at least some of the people who lived at the time of Stonehenge 3 may have come from what is now Wales. An analysis of the crystal polarization has revealed that the stones could only have come from the Preseli mountains.

Aubrey Burl says that the blue stones were not alone by humans, but at least one piece by the glaciers of the Pleistocene of Wales have been transported here. But so far found no geologic evidence for such a transfer between the Preseli Mountains and the Salisbury Plain. In addition, we have found no other copies of this unusual Doleritstone near Stonehenge.
