AMESBURY, ENGLAND – JUNE 21: Revellers dance on the stones as the midsummer sun rises just after dawn over the megalithic monument of Stonehenge on June 21, 2010 on Salisbury Plain, England. Thousands of revellers gathered at the 5,000 year old stone circle to see the sunrise on the Summer Solstice, which is the longest day of the year in the Northern Hemisphere.
