                                The second and most dramatic stage of Stonehenge started around 2150 
        BC. Some 82 bluestones from the Preseli mountains, in south-west Wales 
        were transported to the site. It is thought these stones, some weighing 
        4 tonnes each were dragged on rollers and sledges to the headwaters on 
        Milford Haven and then loaded onto rafts. They were carried by water along 
        the south coast of Wales and up the rivers Avon and Frome, before being 
        dragged overland again to near Warminster in Wiltshire. The final stage 
        of the journey was mainly by water, down the river Wylye to Salisbury, 
        then the Salisbury Avon to west Amesbury. 
                                 
                                  This astonishing journey covers nearly 240 miles. Once at the site, these 
                                    stones were set up in the centre to form an incomplete double circle. 
                                    ( During the same period the original entrance of the circular earthwork 
                                    was widened and a pair of Heel Stones were erected. Also the nearer part 
                                of the Avenue was built, aligned with the midsummer sunrise.)
