This was Christmas Eve about 3:30 - on the tops sunset is near stated time (15:40 approx)
This is Ralphs Cross which is used as an emblem by the NYM Park
It's not especially old though, there is a smaller ugly one called Old Ralph slightly higher up to the south.
There was a wooden cross on this site by the road until about 200 years ago, but the shaft was damaged in the early 80s and is now three sections with the centre one which had a deeply inscribed 'R' having been replaced
