Waun Mawn is a Scheduled Ancient Monument

Photos from 2006 (DAT/ Cadw) and from 2018 showing the recumbent stone supposedly associated with a "slight earth mound."

Thanks to Dave for drawing this to my attention.

Groom, P.  2006  Erosion Control Works at Waun Maun Standing Stones SAM Pe124

I had assumed that Waun Mawn was not a Scheduled Ancient Monument, but it appears that it is!  The number is SAM Pe124.  That means that Cadw must have had some involvement in the consent and monitoring process for the digs on the site in 2017 and 2018.  I shall try to find out what the consent process was (and is) and ask them what they thought of the state of the site when the diggers departed.......

I am also intrigued that some remedial works were undertaken by Cadw in conjunction with the National Park back in 2006 -- involving the laying down of black fabric in "erosion hollows" and infilling with stones and soil and turf taken from a little distance away.  The details of the work are given in the PDF mentioned above.  

Its clear from the Cadw documentation that  Dyfed Archaeological Trust was not very attracted by the idea that there are the remains of a stone circle here.  The only point of potential archaeological interest is the mention of  "a slight mound" in conjunction with their stone 3 (which I have labelled as "stone 1" in my earlier posts).

I have walked across this site many times without seeing any mound at all, and all we can see on close examination is a slight rise in the turf surface on one flank of the stone.  The surface is maybe 10 cm higher than the surface a couple of metres away, and this scale of variation or undulation is insignificant in an area where the ground surface undulates everywhere.  Where there are big erratics lying on the ground surface (or even fallen standing stones) the ground is protected to some degree from ongoing erosion, so I think this is not a matter worth commenting further on.  Neither Cadw nor Dyfed Archaeological Trust personnel thought the matter worth commenting on either.
