From Daily Mail (caution: tabloid):
Mysterious crop circles have been discovered etched into fields in one of the world’s most famous UFO hotspots.
Wiltshire in the UK has become the epicenter of the phenomenon since the 1970s, and the bizarre designs were recently found just 13 miles away from Stonehenge. A perfectly crafted geometric design was spotted in a farmer’s field in the Wiltshire village of Sutton Veny on May 15. The pattern included a central design resembling a Celtic knot or a four-pointed star within a circle.
