Decoding the ancient astronomy of Stonehenge
The Stonehenge monument in England is known for its alignment with the summer solstice sunrise, and a is popular destination for revelers welcoming the longest day of the year. The inner “horseshoe” of the monument opens toward the point on the horizon where the sun appears on the day in June when the sun’s path is furthest North.
But on the same axis, in the opposite direction, is the point on the horizon where the sun sets on the winter solstice. And some experts suspect that the midwinter alignment may have been the more important occasion for the Neolithic people who built Stonehenge.
