Dublin Explorer - Georgia on My Mind: The Shackleton Exhibition. Donal O'Neill of the Shackleton Exhibition held in the former ferry pier in Dun Laoghaire, takes us through what must be the most extraordinary feat of heroism, rescue and survival: Ernest Shackleton's epic 800 mile journey from Antarctica to South Georgia with 5 men in a lifeboat. On arrival they travelled 30+ miles over treacherous, ice-covered mountains to seek the help of Norwegian whalers on the Island's northern shore. Out of a crew of 28, not a single life was lost - just a couple of toes!
