Video buffs looking for crop circle secrets climbed into Silbury Hill in Wiltshire, allegedly damaging the biggest man-made Neolithic mound in Europe. The fields surrounding the hill are where the largest and most intricate crop circles have appeared, and some researchers speculated that some sort of energy was released when the hill opened up last year. Since the event, the most spectacular crop formations in history have appeared.
English Heritage closed the 4,000-year-old mound to the public after an 18th century mining shaft reopened at the top. It has just been discovered that trespassers broke into the site at night, soon after the hole was discovered, because video of the break-in has been included in a documentary film.
