In this episode, Carina reads two of our letters from Ireland. First up we take a look at how Irish placenames receive those names, and the letter is called: "From Cows to River-Mouths". Then, she takes us on a journey along an old Irish road - one that was very important to our ancestors in reaching the markets of Cork City: "Come Back the Old Butter Road".

In this episode of the Letter from Ireland Show, we travel in the footsteps of two Irish scientists - one with a section of the moon named after them and the other responsible for the mathematics behind the computers we use today.
