Stonehenge

Stonehenge is a prehistoric monument located in the English county of Wiltshire. One of the most famous prehistoric sites in Human history, Stonehenge is composed of earthworks surrounding a circular setting of large standing stones. Stonehenge was produced by a culture with no written language, and at great historical remove from the first cultures that did leave written records. There is little or no direct evidence for the construction techniques used by the Stonehenge builders. Many aspects of Stonehenge remain subject to debate. This multiplicity of theories, some of them very colorful, is often called the "mystery of Stonehenge."

The Society of the Ancients suggested Forerunner involvement in the creation of Stonehenge. In addition to suspicion of an ancient people's interest in investing such effort into its construction, the circular shape was used as evidence to support their claim. Many of their proposed artifacts that were affected by alien interventions consists of items with the familiar circular pattern used in Forerunner glyphs.
