Stonehenge is a prehistoric monument in Wiltshire, England, consisting of a ring of standing stones, each around 13 feet high and weighing 25 tons. Built between 3000 BC and 2000 BC, it is a marvel of Neolithic engineering and artistic planning. The stones are aligned toward the sunrise on the summer solstice and the sunset on the winter solstice, suggesting it served as a sophisticated celestial observatory or a site for religious ritual. One of the greatest mysteries is how the builders transported the 'bluestones' from the Preseli Hills in Wales, over 150 miles away, without modern technology. In the 12th century, legend attributed the monument to the wizard Merlin, but modern archaeology reveals it was a communal effort spanning generations. Stonehenge remains a powerful symbol of early human creativity and their desire to connect the physical world with the movements of the stars.
