The British Museum has an exhibition on Celtic art and identity
I just went the other day to finish off my vacation in London (and a few other places) that I was on for about a week, and I must say that it was quite interesting, and somewhat relevant to what I'm learning here on DuoLingo. None of the souvenir books were written in Gaelige, but there were quite a lot of historical fictions and mythology compendiums written in English taking place in Ireland. If you're going to be in London before February '16, I recommend taking a look at it. http://www.britishmuseum.org/whats_on/exhibitions/celts.aspx is more reading.
very interesting.... I probably wont go to London soon though. It does seem that they should write some of the books in Gaelic though, that would be an awesome souvenir!
