The Ghosts of Drimnagh Castle

Drimnagh Castle bears ghostly secrets if we are to believe the legends. Some claim it is haunted by an alchemist that used to live there, some say it is the ghost of Eleanora, who died after a love gone wrong.

In the suburb of Drimnagh outside of Dublin, Drimnagh Castle (Caisleán Dhroimeanaigh in Irish) still stands. This Norman castle is unique in Ireland, boasting the distinction of being the sole surviving castle with a surrounding flooded moat from the Camac River.

The annals of Drimnagh Castle harken back to a time when Ireland was still emerging as a nation. The first recorded owner of the castle was Sir Hugh de Bernival as early as 1216. The legacy of ownership passed through generations, with the Bernival family eventually adopting the name Barnewell, sometimes known as Barnewall.

While the foundations of the castle were initially laid in the mid-13th century, the primary structures that endure today date back to the early 15th century.

Drimnagh Castle remained in the Hatch family’s care until the mid-1950s. Louis Hatch bequeathed the castle to Dr. P. Dunne, the Bishop of Nara, who subsequently sold it for a nominal sum to the Christian Brothers. The Christian Brothers utilized the premises to establish a school, a legacy that continued until 1956 when they relocated to new schools and a nearby monastery.

By the mid-1980s, the castle had fallen into disrepair. Roofs had collapsed, windows were missing, and masonry lay in partial ruin. It was during this period of neglect that Peter Pearson, an artist affiliated with An Taisce (the national trust for Ireland), initiated a local committee’s involvement in a restoration endeavor. FÁS (Foras Áiseanna Saothair), the state training authority, became a vital partner in this painstaking restoration program.

The Alchemist in the Tower of Drimnagh Castle

While Drimnagh Castle has witnessed centuries of history and restoration, it is not devoid of ghostly tales. One of the supposed ghosts haunting the place is the ghost of the Man in Black. Apparently he was an alchemist that worked in the old tower from the 17th century. According to the legend, he made a deal with the devil and for his sins, he had to walk the earth forever.

The most told story though is that about a young girl who is said to haunt the castle to this day. The haunting story that lingers within its ancient walls is that of Eleanora Barnwall in In the late 16th century.

Eleanora’s Descent into Eternal Sorrow

Eleanora Barnwall was the orphaned niece of Hugh Barnewall and destined to wed her cousin, Edmund Barnwall to keep their estates in the family, a man she liked and respected as family, but didn’t love as a man.

Once she went to a party at her friend’s manor in the outskirts of Dublin and Eleanora’s destiny was forever altered. She crossed paths with her true love, Sean O’Byrne. Sean, or Hugh as he is sometimes named was from the O’Byrne Clan of Wicklow, one of the enemies of the Barnwalls and the rest of the Norman families in Ireland. She loved him though, although she didn’t dare to confess to her family and the wedding was happening.

Eleanora and Edmund embarked on a journey from Drimnagh Castle, with much fanfare befitting a noble wedding. Their destination was St. Patrick’s Cathedral, where the grand ceremony was set to unfold.

Sean O’Byrne and his followers descended upon Edmund’s coach when they were halfway there, shattering the dreamlike procession and attacking them. Edmund was killed amidst the tumultuous scene.

In the chaos that unfurled, Eleanora’s uncle, Hugh, grasped the fleeting moments to rally his knights and repel the assault. Many O’Byrnes met their tragic end, and, heartbreakingly, so did Eleanora’s cherished Sean.

Eleanora was thrust back to Drimnagh Castle. Her uncle was livid and he incarcerated Eleanora within the castle’s imposing walls, driven by a maelstrom of emotions—partly out of concern for her safety, but mostly engulfed by an all-consuming anger. In his eyes, she bore the blame for the audacious attack on the wedding party—a stigma she could never escape.

In the dead of night or two after the attack, she managed to escape from the castle and went to Sean O’Byrne’s final resting place, deep within the Dublin Mountains. She clung to the earth that concealed her beloved until she as well died from exposure.

As the winds howled and the snowflakes blanketed her frail form, Eleanora’s sorrowful existence culminated in a haunting tragedy—a tale forever etched into the annals of Drimnagh Castle’s tormented history.
