How Mullaghmore Castle came to be

The history of Classiebawn Castle is an interesting one. The castle was built on what was once a 10,000-acre estate on the Mullaghmore peninsula in County Sligo in the west of Ireland.

Like many Irish castles, Classiebawn passed through many hands over the years. In the section below, you’ll get a speedy insight into the history of the castle, many of those who owned it, and how you can see it today.

The theft of land

Before we get into the story of how Classiebawn Castle came to be, it’s worth mentioning that the land upon which the castle is built was confiscated by the English Parliament from an Irish family.

Yes, that old story once again. The land in Mullaghmore was owned by the O’Connor family, but it was taken by the English to compensate those that succeeded in stopping an Irish rebellion.

When it was built

The building of Classiebawn Castle in Sligo (which was made primarily of stone from Donegal) was started by the third Lord Palmerston, who was once Prime Minister of the UK.

However, he died in 1865, long before the construction of Mullaghmore castle was completed. It wasn’t until his stepson, the first Lord Mount Temple, took over that Classiebawn was completed in 1874.

The early days at Classiebawn Castle

After the first Lord Mount Temple died in October of 1888, the Mullaghmore estate was inherited by his nephew, The Honourable Evelyn Ashley.

When he died in 1888, his son, Colonel Wilfrid Ashley, inherited the estate and became the second Lord Mount Temple.

Before the Irish Rebellion began, Classiebawn Castle was mainly used as a holiday home, of sorts. In the winter, the castle was used as a shooting lodge and in the summer it was used as a base for the family while they fished.

Classiebawn Castle was commandeered by the Irish Free State Army during the rebellion and was used primarily as an army barracks.

A flag was flown and the army protected the castle and its estate. When the rebellion ended, the castle was handed back to Lord Mount Temple.

The Royal Family Connection

Classiebawn Castle has a very strong link to the Royal Family. In 1939, Edwina Cynthia Annette Mountbatten, Countess Mountbatten of Burma inherited the castle.

She and her husband, The 1st Earl Mountbatten of Burma, made a number of upgrades to the castle, like the installation of electricity and the addition of water mains.

The 1st Earl Lord Louis Mountbatten of Burma is Prince Philip’s (yes, the Duke of Edinburgh and Queen Elizabeth II’s husband!) uncle.

Although Countess Mountbatten died in 1960, Lord Mountbatten continued to visit the castle during the summer for many years.

The Assassination of Lord Mountbatten

On a sunny day in August of 1979, Lord Mountbatten was assassinated not far from Classiebawn Castle, while in a fishing boat in the water off Mullaghmore.

Thomas McMahon, a member of the IRA, made his way onto the boat the night before and attached an explosive that could be controlled remotely.

There were a number of people on-board when the explosion went off, including Lord Mountbatten, his grandsons (Nicholas and Timothy) and Paul Maxwell – a member of the fishing crew.

Worldwide outrage

The blast killed Nicholas, Paul, Lord Brabourne’s mother, Doreen, and Lord Louis Mountbatten, sparking outrage across the world.

It’s believed that there was another assassination attempt a year earlier, in 1978. It’s alleged that the IRA attempted to shoot Lord Mountbatten while he was on his boat, but that bad weather prevented a sniper from taking a shot.
