Once the mainland harbor for the Blasket islanders, Dún Chaoin is at the center of the Gaeltacht, and attracts many students of Irish language and folklore. David Lean shot Ryan's Daughter hereabouts in 1969. The movie gave the area its first major boost in tourism, though it was lambasted by critics—"Gush made respectable by millions of dollars tastefully wasted," lamented Pauline Kael—sending Lean into a dry spell he didn't come out of until 1984 with A Passage to India.
