The fact that The Avenue approaches Stonehenge and enters facing the midwinter sunset suggests that Stonehenge was dedicated to the ritual of encouraging the Sun to return from its low point to bring new life in spring. In other words, there is a very real possibility that the monument was dedicated to the midwinter sunset in the south-west, not the midsummer sunrise in the north-east.
.... and the fact the faces of the stones seen when approaching from the Avenue are finely dressed on that side increases it to a probability.
