This is exactly the sort of offbeat destination my husband likes to pick, & as usually happens, I enjoyed it, despite having doubts going in. The museum is in the old Butter Exchange building in Cork, and exactly what the Butter Exchange was & why it was central to Ireland's success gets clearly explained.

There's a video of old-fashioned churning (wish there'd been a demonstration or a try-it-yourself, but understand that would be very expensive), testimonies of fairies & witches 'stealing' the butter from the churns, all sorts of historical tools, displays about the history of cattle stealing -- and the crock of 1,000 year old butter. I kid you not.

So, if you want to know what exactly Kerrygold butter is, and why it tastes so good (mmm, Irish butter), spend a little time here. It's worth it.
