Last weekend in Glastonbury, England, on a site covering 1,000 acres, the 40th annual Glastonbury Festival was held at Worthy Farm. Started by a dairy farmer, Michael Evis in 1970 it has grown into the largest music festival in Europe. This year's headline acts on the main stage included Muse, Gorillaz and Stevie Wonder. Thousands of attendees were treated to a sunny weekend in the country with plenty to see, hear and experience. Collected here are 40 images from Glastonbury 2010 for its 40th anniversary.
