Stonehenge is located in England, in the county of Wiltshire.
The prehistoric monument stands on Salisbury Plain, about 13 kilometres north of Salisbury. It consists of earthworks and several circles or arrangements of standing stones, including enormous sarsens and smaller bluestones transported from Wales.
Construction took place in several stages between roughly 3100 BC and 1600 BC. The monument's builders left no written explanation, so researchers study its alignments, burials, tools, and surrounding settlements to understand its ceremonial and social importance.
Stonehenge is sometimes described as being in Britain or the United Kingdom, but the most specific country answer is England. It is managed as part of a wider archaeological landscape and was inscribed on the UNESCO World Heritage list in 1986.
