Why not use our original Irish language placenames when posting a letter in Donegal? To assist you, we have provided a list of the main placenames and population centres in Donegal. It is our intention to add to this list over time. If you have any suggestions, or any local placenames you would like to add, please forward them to our Irish Language Development Officer, Seán Ó Daimhín, at sdaimhin@donegalcoco.ie
