I have just bought an old postcard shoing a battered tomb with the caption "Dyffryn, Cromlech". It doesn't appear to be one of the Dyffryn Ardudwy chambers.

Does anyone know if there was another tomb in the area that has been destroyed in the last, say, 100 years?

I did think it may have been Cors y Gedol, but the capstone doesn't match - unless the capstone is now upside down.

I'll post a pic later on, but I just wanted to get the thought processes going.

I will also post a picture taken during excavation of Dyffryn Ardudwy showing one of the most blatantly willy-like stones I've ever seen in the courtyard of the east chamber.
