Butter is more important to Ireland's economy than you may realize. In fact it's so important that they have a museum dedicated to it's rich history.

In Limerick, King John's Castle stands as an historic fortress and landmark, and it's playing a substantial role in Ireland's future as well. Plus, you'll meet someone with definite opinions of King John, and someone you may recognize from the Game of Thrones.

All that plus A Broad Abroad...in Episode 9 or Erin's Isle.
