Searching for sieidi stones

I think I found another one:  http://en.m.wikipedia.org/wiki/Aibell
This Wikipedia page describes a place in Ireland that I think was used just as the sieidi stones.

I am hunting for places that would have had magic in ancient times.  It's not really the magic that I'm after-  I just want to find out what life was like in the 200,000 years before written history.

So here's my list of places I've found (and there should be many more.)
--Serre da Estrela, Portugal

--Montserrat, Catalonia, Spain

--Craig Liath, Kilaloe, Munster, Ireland

Here's the link to the acoustic archaeology research about sieidi stones:
