Dublin, of course, has one of the strongest Irish-language cultural scenes in Ireland. There are bookshops, shows, Irish schools, and a host of other activities and resources as well as a fairly large population of people who use Irish in their everyday lives and their work. Unfortunately, Leinster Irish as an entity doesn't really exist because the Gaeltacht areas in Leinster died out quite early. There were vestigial areas of Irish-speaking at the beginning of the 20th century but generally, Irish speakers in Leinster speak Ulster, Connaught or Munster Irish. They go to courses in the other provinces to learn the language. However, one of the most important and best books ever written in Irish was written in Leinster Irish in the Leinster county of Kilkenny. It was a diary kept by Amhlaoibh Ó Súilleabháin, a small shopkeeper and teacher, in the 1820s. It is a fascinating book from the point of view of social history and I would recommend anyone to get a copy and read it!
