The Mariners' Church in Dun Laoghaire, built in 1837 and for generations of Church of Ireland people, the heart of their cultural, spiritual and social life. It closed in 1971, its congregation dwindling away. So what happened to all its parishioners who had lived in the streets and squares of Dun Laoghaire or Kingstown as it was called? The Mariners Project is Julie Parsons’s quest to find out.
