Silbury Hill is a man-made hill in legendary Wiltshire County, England. It is part of a landscape that boasts the Roman Road, Stonehenge and numerous other feats of long ago man. It dates back to roughly 4,750 years ago and was built by an unknown society. It is the largest of such hills in England, taking up about five acres and standing 131 feet in height. It may have even been taller when it was built, as the summit is now leveled off, though thought to have been originally rounded.
