Plas Teg — The Most Haunted House in Wales
Sir John Trevor's c.1610 Grade I Jacobean house is the standard-bearer of Welsh ghost canon: a grey lady who steps in front of traffic on the A541, a canon of some fifteen resident ghosts, and two national TV paranormal investigations.

FILE 01 The Legend
Plas Teg — 'the fair hall' — was built about 1610 by Sir John Trevor I, a prominent courtier of King James I, and is one of Wales's finest Grade I listed Jacobean houses, sitting between Wrexham and Mold at Pontblyddyn in Flintshire. Sir John died in 1630, his wife in 1643, and the house was left unoccupied as the English Civil War broke out; it was twice raided by the Roundheads — a genuine turbulence the ghost canon grew from. The signature entity is the grey lady, described in the literature as the most popular such figure in North East Wales: an old woman repeatedly reported moving across the A541 road that runs past the house, stepping into the path of traffic — a roadside apparition with decades of retellings among drivers. The house's canon runs to a claimed fifteen ghosts with tragic tales attached: the hanging of a woman (said to be a judge's wife or daughter, tellings vary) whose rope-swing ending is retold on tours, a small boy, a housekeeper, and figures in the panelled rooms — the WalesOnline canon piece counts fifteen. The modern media layer is unusually strong for Wales: Plas Teg featured on ITV's 'Extreme Ghost Stories' and on Living's 'Most Haunted' (the house is routinely billed 'one of the most haunted houses in Wales'), and in 2006 the Western Mail even recorded the pop group Girls Aloud's haunted-mansion ordeal filmed there; the house later passed through Channel 4's 'Country House Rescue' and 'Obsessive Compulsive Cleaners' episodes as its then-owner Cornelia Bayley, who bought it in 1986 for £75,000 and restored it with Cadw support, opened it to the public. The book layer exists in Mark Baker's country-house biography of Plas Teg and regional haunted-Wales collections that treat the grey lady as the region's definitive roadside ghost.
FILE 02 The Sightings Log
The documented record: the grey lady's recurring appearances on the A541 recorded in the canon literature and retold by WalesOnline; the fifteen-ghost roster with the hanging woman, the boy and the housekeeper; the ITV Extreme Ghost Stories and Living Most Haunted broadcasts; the 2006 Girls Aloud filming episode reported by the Western Mail; and decades of public ghost tours under Cornelia Bayley's ownership after her 1986 purchase and restoration.
FILE 03 The Skeptic’s File
No aspect of the Plas Teg canon survives contact with a records office: the hangings and tragic deaths are tour tellings without documented victims, the grey lady is a roadside legend of the A541 that thrives because drivers pass a lit, turreted Jacobean pile at night, and the TV investigations are entertainment products. The house's real, documented drama is architectural — a Grade I survivor of Civil War raids and dry rot — and its owner's long public battle to fund it, which the ghost economy demonstrably helped.
