P 37 / 38 has an entry on Maen Beuno SJ 203013 (visited March 2003 on a meet) describing it as a Christianised outlier, mentioning the field nearby where we gazed for remains of a henge, for 10 mins or so. This book mentions 3 "ring-ditches"! Top of p 38 there is an aerial crop photograph that clearly shows one sizeable 'henge outline', one smaller, and one very faint.
