Stonehenge
Stonehenge is a prehistoric monument in England consisting of a ring of massive standing stones, believed to have been constructed in several phases beginning around 3000 BCE.
The site's construction spanned centuries, with the massive sarsen stones, some weighing up to 25 tons, believed to have been transported from quarries roughly 20 miles away, an extraordinary feat for the technology of the time.
The purpose of Stonehenge remains a subject of ongoing archaeological debate, with theories ranging from a religious and ceremonial site to an astronomical calendar, given its alignment with the solstices.
Stonehenge was named a UNESCO World Heritage Site in 1986 and remains one of the most visited and studied prehistoric monuments in the world.
