The house on the hill
Classiebawn Castle
The gothic-revival pile above the village was built between 1856 and 1874 for Lord Palmerston, the British prime minister, on land his family had owned since the 1600s. It passed by inheritance to the Ashley and then the Mountbatten families. Lord Mountbatten — uncle of Prince Philip, last viceroy of India — summered there for decades. The castle is privately owned and not open to the public; you see it best from the loop road on the headland.
27 August 1979
Shadow V
On a bank holiday Monday in August 1979, the Provisional IRA planted a bomb on Lord Mountbatten's wooden fishing boat, Shadow V, while it was moored in Mullaghmore harbour. The device was detonated by remote control a short distance out from the head. Mountbatten was killed, along with his 14-year-old grandson Nicholas Knatchbull, 15-year-old crewman Paul Maxwell, and the Dowager Lady Brabourne, who died of her injuries the next day. The village still carries the day quietly. There is a small memorial on the pier.
How the big-wave map got redrawn
Prowlers and the head
The reef off Mullaghmore Head produces one of the heaviest big-wave waves in Europe when a deep Atlantic low lines up against the right swell direction. The break called Prowlers, a few kilometres offshore on a separate shoal, only fires a few times a year. Tow-in crews started coming in the mid-2000s. Conor Maguire from Bundoran, riding for Red Bull, was nominated for the World Surf League's Ride of the Year for a roughly 60-foot face he caught here on 28 October 2020 during the Hurricane Epsilon swell. The wave is for watching from the cliffs, not paddling out into. Wear a hat that won't blow off.
The harbour the famine built
Palmerston's pier
The pier at Mullaghmore was built in the 1840s as part of Lord Palmerston's improvements to his Sligo estate. The work coincided with the Great Famine and was carried out partly as relief employment. The same Palmerston also organised the assisted emigration of around 2,000 of his tenants to Canada during those years — the ships that left from this coast became one of the more documented chapters of the period's emigration history.
