Silbury Hill
Silbury Hill had a 40 meters high (131 ft) which makes it one of the largest in the world. The original purpose of construction of so high hill is still unknown but there are many theories from representatives of the official historical schools and from the New Age philosophers and writers. Independent researchers of ancient civilizations do not have a big interest in Silbury hill because there are no any evidences of ancient high technologies. But it’s the biggest mound in Western Europe.
