Ráth Bhoth · Co. Donegal
A cathedral town that was important before Derry existed.
Raphoe was a seat of ecclesiastical power before most of Donegal had a town worth naming. The diocese was established in the 12th century but the monastic site goes back to Colmcille in the 6th - the same saint whose shadow falls over Glencolmcille, Iona, and half of early Christian Ireland. That long tail of importance is the reason Raphoe has a cathedral and a bishop's palace ruin and a plantation diamond all within a short walk of each other.
It's a quiet town now. The east Donegal Laggan district runs to farming and small industry. But the built fabric is genuinely old and the town wears its history without making a fuss about it - which is more than you can say for places with heritage centres and admission charges.
