Stonehenge is a prehistoric megalithic structure on Salisbury Plain in Wiltshire, England, two miles (3 km) west of Amesbury.It consists of an outer ring of vertical sarsen standing stones, each around 13 feet (4.0 m) high, seven feet (2.1 m) wide, and weighing around 25 tons, topped by connecting horizontal lintel stones, held in place with mortise and tenon joints, a feature unique among ...
This is the first evidence for any unambiguous alignment at Stonehenge (the solstice axis). The analysis of the spacing between the Q and R array, and that of the modified (inset) portal group (Fig.3) imply a shift from an angular splay of 9 degrees (i.e. 40 settings) to 12 degrees, the same as that of the later 30 Sarsen Circle.
