Thank you Rebecca and Theo,
You have answered a question that I have been puzzling over and not been able to find the answer too. Whereas I saw plenty of pellotta courts in the Basque region and also Boule "courts?" too, this was the only time that I saw this particular game being played and no-one has had the answer to its name. With the size of the playing area it is evident that it is very poplular in that region. The path runs right beside the playing area, and what I presume to be the "club house", and I have no doubt that others have wondered what it is used for.
Thanks again, Janet
