The ancient structure located in Stonehenge, England, is a prehistoric monument made of a ring of standing stones. Dating back to the Neolithic and Bronze Ages, Stonehenge is believed to have been constructed between 3000 BC and 2000 BC. Its purpose has been a subject of much debate, with theories suggesting that it may have been used for ceremonial or astronomical purposes, possibly related to solstices. The stones, some weighing up to 25 tons, were sourced from as far as 200 miles away. Stonehenge remains a UNESCO World Heritage Site and an emblem of prehistoric engineering and culture.
