The Lammas tower could fit with the Burren ones, but I'll have to wait and revisit them before I say for certain. I know that there used to be a Lammas Fayre at Poulawhack cairn in the Burren until quite recenlty, but the curricks I saw are in the middle of nowhere on the limestone pavement. I think you would need to have a field hospital nearby if you held a procession to one of them.

I do think that some of the stone forts in the Burren weren't forts but were meeting places or gaming arenas. The association with fairies playing Hurley in them is very common. It is <i>just</i> possible that some of them were built for one off games (perhaps the games moved from townland to townland each year for fairness). A lot of them are over looked by cliffs etc that would make them useless from a defensive point of view. As with most of the things like this that I say this is purely my speculation, with little more than observation and a little folklore to go by.

The phallic beastie looks as if it's had the top broken off at some point in time (over zealous priest? It's well documented to have happened in Ireland) and the stones are just a rebuild. Of course it could just be a 1972 addition by a walker with a sense of humour :-)
