Great Lighthouses of Ireland

Ireland’s lighthouses are vital to the nation’s survival. As an island nation, almost everything we consume from food, to electronics, fuel and vehicles arrive by sea. Lighthouses aid the safe passage of ships around our dangerous coastal waters. The story begins at Hook Head, a treacherous peninsula known locally as “The graveyard of a thousand ships”. Hook Head is home to a 800-year-old lighthouse: the oldest working lighthouse in the world.

In the second episode, we discover how Ireland became a world leader in lighthouse engineering. Often working in hostile and treacherous natural locations, Ireland’s lighthouse engineers and builders used great ingenuity to achieve what seemed impossible.

In the third episode, we discover the surprising roles that lighthouse keepers played in both World Wars. As the First World War raged around Ireland’s coast, our lighthouse keepers acted as unofficial coastguards, keeping detailed logs of their observations. In the Second World War an Irish lighthouse keeper played a decisive role in the outcome. We travel to Blacksod Bay, Co. Mayo where in 1944 lighthouse keeper Ted Sweeney took a weather reading which was to determine the entire timing of the allied invasion on D Day.
