Set among the low-lying fields of North Tipperary stands Lackeen Castle, a 16th-century tower house with a remarkable history. During work on the building in the 1700s, a manuscript was discovered hidden inside a wall cavity. It proved to be the Stowe Missal, an 8th/9th-century Mass-book and one of the most valuable early Christian manuscripts in Ireland. Now housed by the Royal Irish Academy, it remains the castle’s most famous archaeological treasure.

Yet Lackeen preserves another legacy—one rooted not in vellum and ink, but in folklore. Tradition holds that the castle was once home to a púca, the shape-shifting spirit known throughout Irish mythology.

Local storytellers say the tale began when three old women, described variously as cailleacha or bean feasa—wise-women associated with charms and remedies—were seen taking items from the body of a man who had collapsed in the grounds. A member of the O’Kennedy family confronted them and noticed that they were being guarded by a púca.

Accounts differ on the spirit’s form. Some say it appeared as a black horse, others as a tall shadow, and in one telling it was small enough to be trapped in a leather sack. Whatever the shape, the O’Kennedy man is said to have captured the creature—an act which, according to tradition, invites serious danger. Servants pleaded with him to let it go, and the púca itself supposedly warned that harm would follow unless it was freed, though the O’Kennedy family would remain safe. The warning was taken seriously, and the creature was released into the night.

But the púca, the story goes, never truly left. Generations of locals spoke of a black horse galloping across the fields and vanishing when approached, or the sound of hooves pounding around the ruins when no animal was nearby. Visitors have reported sensations like a tail brushing against their legs, and flickers of blue light moving across the battlements on storm-filled evenings. Depending on who tells the story, the púca is either a protector of the site—or a mischievous force that lingers.

Lackeen is also associated with the ghost of a woman in white. She is said to drift through the upper rooms, sometimes appearing silently on the stairs before fading away. Some believe she belonged to the Kennedy family; others think her origins lie further back in the castle’s history.

There are traditions of battle sounds too—clashing steel, shouted orders, the rush of hooves echoing across the grounds. While no specific conflict is recorded on the site, the O’Kennedy lands were contested for centuries, and folklore often preserves memories where history has gaps.

Modern paranormal groups have also turned their attention to Lackeen. Paranormal Supernatural Investigations Ireland visited in August 2022 and released a photograph that appeared to show a figure at one of the barred windows, though nothing was visible at the time. They reported cold spots, strange noises, and a strong sense of being watched.

Paranormal Awakenings Ireland carried out their own investigation in May 2023 and released a recording which they interpreted as a voice saying “Help me.” A medium present suggested a tragic death might be connected with the site. It should be noted that no such event is documented historically, and that interpretation relies solely on mediumship, yet the recording certainly reinforced Lackeen’s reputation.

Today the castle stands in peaceful countryside, but the stories surrounding it remain very much alive—from medieval manuscripts to shape-shifting spirits and spectral figures that linger in the stairwell of this atmospheric Tipperary stronghold.
