These sports which are popular in only one specific region (or several regions) are really fascinating. For instance, I had to visit Ireland first to learn about Gaelic football (https://en.wikipedia.org/wiki/Gaelic_football), which seems to be a mix of soccer and rugby and is immensely popular in Ireland (the largest stadium in Dublin, which is also the third largest in Europe, is used primarily for it), but pretty much unknown anywhere else.
