This one was part of a wall at Howdale I was rebuilding. I replaced the stones in their previous order and position. This was in 2010. Early in spring this year I was leading a wildlife walk and for the 1st time noticed the circular'cup and ring' marks on the right end of the lintel. These marks occur in many places in the UK, and can be found in substantial numbers on the nearby moorland.
This is not the only archelogical find in this wall. I also discovered a cope stone with several 'cup' marks on one side. But that I noticed and recorded at the time of finding it.
