A small museum next to St Anne's that turns out to be unexpectedly engaging — the story of how Cork came to dominate the world butter trade in the nineteenth century, with the Cork Butter Exchange the largest of its kind in the world. Exhibits explain the firkin-grading system, the cooperage that supplied the barrels, and the role of the Munster dairy industry in feeding Britain and its empire.
