| Ninety miles west of London and twenty miles north of Stonehenge stands Avebury, the largest known stone ring in the world. Older than the more famous Stonehenge, and for many visitors far more spectacular, the multiple rings of Avebury are cloaked with mysteries which archaeologists have only begun to unravel. Similar to Stonehenge and many other megalithic monuments in the British Isles, Avebury is a composite construction that was added to and altered during several periods. As the site currently exists, the great circle consists of a grass-covered, chalk-stone bank that is 1,396 feet in diameter and 20 feet high with a deep inner ditch having four entrances at the cardinal compass points. |
