Day of revelry.
A reveller is pictured as people gather to celebrate the pagan festival of 'Summer Solstice' at Stonehenge in Wiltshire in southern England, on June 21, 2011. The festival, which dates back thousands of years, celebrates the longest day of the year when the sun is at its maximum elevation. Modern druids and people gather at the landmark Stonehenge every year to see the sun rise on the first morning of summer.
