In the rural areas of Derry, Northern Ireland, there is a small dolmen grave under a hawthorn tree. It is said to be the grave of the vampire king, Abhartach who is said to still be lusting after blood.
Ireland’s ancient hills and mossy graveyards are no strangers to ghost stories and restless spirits. Yet among these tales of banshees and fairies lies one of the island’s oldest, darkest legends — the story of Abhartach, a tyrant chieftain whose insatiable thirst for blood refused to end, even in death.
Thought by some folklorists to be Ireland’s original vampire myth, Abhartach’s grim story predates Bram Stoker’s Dracula, and may well have been its inspiration.
The Tyrant of Slaghtaverty
According to legend, Abhartach was a cruel and malevolent chieftain who ruled in what is now Slaghtaverty in the parish of Errigal in Derry, Northern Ireland. Although he is remembered as a vampire, the name and description of him is much closer to a dwarf. As the name suggests, he might have been remembered for his height.
He is said to have lived in the 5th or 6th century, at a time when the Glenullin area of Ireland was a patchwork of small kingdoms of tribal warlords were the mysterious druids still lived and practiced their magic and when the catholic saints started settling on the emerald island.
Feared by his own people, he was said to possess dark powers and a fascination with the occult. Through his practice of dark magic, he killed his subjects for fun. His tyrannical ways became so unbearable that local warriors, desperate for relief, conspired to kill him.
In one version of the tale, a neighboring chieftain named Cathán rose up against Abhartach and struck him down, burying him in a standing grave, marked by a solitary stone. Burying in a standing position was a custom at the time for high-ranking chieftains. But peace would not come so easily.
In other versions his first death was through no fault but his own and he died when he was stalking his wife. He was a jealous man and trusted no one. He thought she was having an affair and crept on the ledge outside of the castle to the window outside her bedroom. He slipped and fell to his death and they quickly buried him for the first time. But it would not be his last.
The Undying Menace
The day after his burial, Abhartach returned — clawing his way out of the earth, demanding blood from his terrified subjects to collect in a bowl for him to consume. In some versions of the legend, his subjects were so afraid of him and submitted to him, making blood sacrifices to him, waiting for someone to save them.
Again, Cathán slew him, and again, Abhartach returned. It was then the people sought counsel from a druid or wise elder who revealed the grim truth: Abhartach was no ordinary man, but one of the neamh-mairbh, the undead. In more modern retellings of the story it was a Christian Saint giving the solution to the undead.
To stop his monstrous resurrection, he could not be buried in consecrated ground. Instead, he must be killed with a sword made of yew wood, buried upside down, and his grave encircled with thorns and heavy stones to prevent his escape.
Cathán followed the instructions, and Abhartach was finally trapped — but local legend holds that his restless spirit still lingers beneath the earth.
The Cursed Grave of Slaghtaverty
According to a lecturer in Celtic history at the University of UIster, Bob Curran, the real castle he lived in an be found between the towns of Garvagh and Dungiven, where a small hill now stands. He says that it was here that the fortress of a 5th or 6th-century chieftain with magical powers called the Abhartach once resided.
Today, the place believed to be Abhartach’s grave is a modest site known as Slaghtaverty Dolmen or The Giant’s Grave. Nestled in a field near the village of Slaughtaverty in Londonderry in Northern Ireland, it’s marked by an ancient stone surrounded by a ring of Hawthorn trees and undergrowth. It used to be more stones as remnants of an old monument, but these have been removed over time by local farmers for building purposes.
Locals claim the spot is cursed; farmers avoid working the land around it, and strange misfortunes are said to befall those who disturb the grave. Some say on misty nights, you can hear faint whispers, or catch the flicker of a shadow moving between the trees — as though Abhartach himself still walks, searching for blood.
In 1997, attempts were made to clear the land, but, if local tradition is to be believed, workmen who tried to fell the tree found that their brand-new chainsaw stopped for no reason on three occasions. When attempting to lift the great stone, a steel chain suddenly snapped, cutting the hand of one of the labourers and, significantly, allowing blood to soak into the ground.
The Dracula Connection
We first have the legend written down in Patrick Weston Joyce’s The Origin and History of Irish Names and Places from 1870. In modern versions of the lore, the story is said to be solved by an earlier Christian, and not a druid.
Intriguingly, scholars have speculated that Abhartach’s legend may have inspired Bram Stoker’s Dracula. Stoker, an Irishman born in Dublin, would have likely been familiar with the story of the blood-drinking undead chieftain. While Dracula is commonly associated with Vlad the Impaler and Eastern European folklore, it’s possible that the sinister figure of Abhartach left its own mark on Gothic horror’s most famous vampire.
