Although this interesting and unusual double cromlech is situated within the private grounds of the house it is quite visible from a short distance. I was lucky enough to get up close to it, fleetingly, and get a better look. There’s some debate as to whether the smaller cromlech is an antechamber to the larger or if it’s a burial chamber in it’s own right. The guy that I was talking to there also seemed to think that the whole thing might be slightly fanciful and possibly re-erected by over zealous Victorian antiquarians. Not unknown by any means. It’s certainly very large with massive capstones, well sited and would have had commanding views over the Menai Strait before the house was built, and probably witnessed the destruction of the Druids by the Roman army just a bit further North up the strait.
