Stonehenge is located in Wiltshire, England, about 8 miles north of Salisbury. This prehistoric monument is composed of a ring of standing stones, each around 13 feet high and weighing several tons. Believed to have been constructed between 3000 BC and 2000 BC, Stonehenge has been a subject of intrigue and research. Its purpose remains still uncertain, but theories range from serving as an astronomical observatory to a ceremonial site or burial ground. Stonehenge is now a UNESCO World Heritage Site, attracting hundreds of thousands of visitors each year who marvel at its historical and cultural significance.
