Stonehenge, located in Wiltshire, England, is a famous prehistoric monument consisting of standing stones arranged in a circular formation. It was built in several phases starting around 3100 BC and served as a burial ground. Stonehenge is aligned with the summer and winter solstices and is surrounded by other ancient monuments. Considered a British cultural icon, it has been protected since 1882 and is now managed by English Heritage. The site's name possibly comes from Old English words meaning "stone hanging" or "suspended stones."
