Lads,

Some of ye may have remembered me talking about an interesting site in Limerick / Tipperary.

Well it seems to be up and running. I have to say its an unusual site.
What I can vouch for is the amphitheatre effect and the very unusual effect that one part of the site has in terms of sound.
Have a look through it, it lists ring-forts, bullaun stones, a church and fulacht fiadh so from that it would seem to be early christain.

However I know the owner thinks it is much older. I havent been to see it since it has been open. Will be interesting what he says in the tour because the website he has above is a toned down version of what he reckoned it was at the time we chatted.
