Went over to Stanton Drew Stone Circles with my daughter to experience the setting sun on the Winter Solstice. There were a few others at the Stones but not many. Unfortunately the sun was somewhat obscured by clouds although there was a 'red sky'
There appears to be an alignment through the 'Big Mound', the north east avenues, across the Great Circle to the south west circle where the sun seems to set. This is enhanced by the upward slope to the horizon looking towards the setting sun. Standing in the avenues, the south west wind blows into your face, as you look in the direction of the setting sun the clouds appear to pass rapidly by on either side, the 'red' rays of the sun take centre stage - and then it is gone as the sun dips below the horizon.
I guess it can be considered a spiritual experience.
