The ancient civilization known for the construction of Stonehenge is the Neolithic people of prehistoric Britain. Stonehenge, located in Wiltshire, England, is estimated to have been constructed around 3000 BCE to 2000 BCE. This megalithic structure consists of large stone circles arranged in a specific pattern, which suggests its use for ceremonial or astronomical purposes. The exact functions of Stonehenge remain a subject of speculation and research, with theories proposing it served as a burial ground, a place of worship, or an astronomical observatory. Its construction reflects the ingenuity and cultural practices of the Neolithic society.
