Kilmainham Jail is where they held the rebel leaders and executed them after the uprising, so you'd probably enjoy that - the Book of Kells at Trinity College would likely be right up your alley, too.

I keep trying to talk my husband into doing a literary pub crawl, too - they have guided tours where they'll take you to famous writers' favorite watering holes, and I've always sort of wanted to see the pubs where Yeats and Joyce (among others) drank and wrote. :)
