Err, Greywether, the ring cairn is Circle 278, at least according to Frances Lynch, who published a diagram of it in "Prehistoric Wales". What we want to know is, the correct name (or inventory number, or site number), for the prominent stone assembly that most folk (including us), thought was circle 278, and to which monument class does it belong?

The two closest hits on CARN to "the monument formerly known as circle 278", are both listed as enclosures, one prehistoric and one "period unknown", when you consider that the locations given for these are within 30m of each other, perhaps you will see why accurate location may aid in discrimination.

A recent topic has been the inaccuracy of much of the information presented on the internet. We(and many others including MA), have incorrectly presented the above monument on the web as Circle 278 for some time now. I'm sure you can understand our wish to correct this error and our deisre to identify and describe the monument correctly this time.
