Stonehenge may have aligned with the moon as well as the sun

When it comes to its connection to the sky, Stonehenge is best known for its solar alignments. Every midsummer's night tens of thousands of people gather at Stonehenge to celebrate and witness the rising sun in alignment with the Heel stone standing outside of the circle. Six months later a smaller crowd congregates around the Heel stone to witness the midwinter sun setting within the stone circle.
