I was going on yesterday about the strange exclaves of Spain that are dotted along the North African coast. A similar situation exists to the North of the country.
The village of Ferns (also pop 1500ish) Co Wexford is also in some sense a city. It gives its name to the Catholic Diocese of Ferns although the bishop has shifted his seat down the road to St Aidan's Cathedral in Enniscorthy. There was a Church of Ireland Diocese of Ferns as well, but the CoI dioceses were rationalised a while back and Ferns was subsumed into the united Diocese of Cashel and Ossory. That seemed sensible because otherwise there would have been a 1:1 ratio between bishops and the remaining practicing protestants. Nevertheless there is still St Edan's Cathedral, Ferns which looks like any other CoI parish church. Aidan/Edan? Somebody can't spell, but I'm not taking sides on that one.
Ferns was named as a bishopric because it was big and important enough in medieval times to warrant this distinction. All the stars of children's book history hung out there. It was the capital of the Dermott MacMorrough's Kingdom of Leinster, William Marshall built the castle, and Strongbow's daughter was married there. But nobody claims that it was bigger than, say, Winchester, Ipswich or Nottingham across the water. In 1337, these all had populations of about 1500 people just like Ferns today and maybe like Ferns back then.
I'm afraid we've missed (ooops I blinked) the Ferns contribution to The Gathering which all happened a month ago at the beginning of June but it's never too late to send a delegation to visit Llivia and exchange Keys to the Cities.
