In a world around which the Universe rotates, the Sun moves its plane (circle) up and down along the polar axis. In summer, the plane is high over England, so the days are long. The sun’s circle rises from the north east and sets in the north west. In winter, the plane is low, so the sun’s circle rises from the south east and sets in the south west:

If we expand the Earth to make it easy to visualise:
Then this layout is identical to Stonehenge’s layout:
