Going by the name alone this could make it onto any list entitled “world’s oddest museums,” but the quirky little Cork Butter Museum isn’t merely a celebration of tasty Irish dairy produce. From 1770 until the 1920s, Cork was actually the largest exporter of butter in the world, peaking at half a million casks annually by the turn of the 20th century. The museum chronicles that industrial past, using butter as a springboard to explore wider stories about Irish farming, society, and industry, from the middle ages onwards. It’s an oddity, for sure, but a charming one.
