The Hellfire Club — The Devil's Card Table
A ruined 1725 hunting lodge on a Dublin mountaintop, built from the stones of a 5,000-year-old passage tomb and leased to an aristocratic club whose card games legend says Satan himself joined.

FILE 01 The Legend
William Conolly, Speaker of the Irish Commons and the richest commoner in Ireland, built a hunting lodge on Montpelier Hill in 1725 — roofing it, tradition holds, with stone robbed from the passage cairn already on the summit. After his death the lodge hosted the Dublin Hellfire Club set of the 1730s-40s, the blazer-and-blasphemy circle around the first Earl of Rosse: the Order of the Blasters, whose exploits moved contemporary newspapers. The stories that stuck are the strongest in Irish folklore: a stranger joining a card game in a locked room, revealed by spilled drink as the Devil as he vanishes up the chimney, leaving a cloven hoof-score in the table; a servant set alight for the amusement of drunk members; a member's bet that he could raise the Devil answered by a cardinal who frightened the house to silence. The lodge burned in the 1740s and has stood as a roofless box on the skyline ever since — a national monument above Dublin where every teenager in the city has at some point driven up to be frightened. Since 2019 the Abarta Heritage community archaeology project has been excavating the hill, and found the deepest story of all: the cairn the lodge robbed was a Neolithic passage tomb, making the haunted hill older than the pyramids' neighbours.
FILE 02 The Sightings Log
The canon is stable: the card room's cold hearth lighting itself; a black mass of shadow inside the roofless shell on moonless nights; the Devil's hoofprint in a stone kept in a nearby pub; and motorists on the hill road reporting a figure in the ruin that stays when the headlights pass.
FILE 03 The Skeptic’s File
The Hellfire clubs were real and genuinely obnoxious — duels, blasphemy, and a servant-burning episode appears in contemporary Dublin gossip — but the Satanic card games trace to club members' own deliberate self-mythologising, printed and reprinted until folklore filed it as fact. The archaeological reading is better than the ghost: a tomb 5,000 years old was stripped to roof a party house, and the mountain remembers. Between the two, Dublin invented its haunted hill twice — once in the Stone Age, once in the gin age.
