Stonehenge

Stonehenge, England.

Stonehenge consists of a ring of enormous stones (some of which originated in Wales) built in stages beginning 5000 years ago.  The stones weigh up to 4 tons each.  The inner horseshoes are aligned along the sun’s axis on rising in midsummer and setting in midwinter.  Despite the site’s sun influence, little is really known about Stonehenge’s purpose.  It is referred to as the greatest mystery of the prehistoric world.
