Bigger than Stonehenge, the site of Avebury just 17 miles north of Stonehenge consists of a massive stone circle 331.6 meters (1,088 ft) in diameter with two avenues of stones leading to a pair of smaller stone circles. Construction began around 2900 BC, roughly the same time as its neighbor. Other monuments, such as the mysterious artificial mound of Silbury Hill and the West Kennet Long barrow, an ancient tomb, are an easy walk away. During the Middle Ages the locals got religion and decided this pagan monument needed to go. They knocked over several stones until one fell over and crushed one of the vandals. Everyone thought this was just a legend until modern archaeologists dug up a fallen stone and found the skeleton of a man underneath with some 14th century coins in his pocket!
