Vox's Joss Fong assembles a scale model of Stonehenge and explains some of the ancient monument's geometry, the geology of the stone it's built from, and the its possible astronomical significance.
Stonehenge is a popular destination for summer solstice celebrations because the 5,000-year-old monument points toward the summer solstice sunrise on the horizon. However, it also points to the winter solstice sunset in the opposite direction and there's good reason to believe that this may have been the more important alignment for the Neolithic people who built Stonehenge. We investigate by constructing a tiny model of the Stonehenge monument.
