A stately home thought to be one of the most haunted houses in Britain has been opened to the public.
A ghostly figure in front of this visitor? Or a trick of the camera?
Plas Teg in Pontblyddyn, near Mold, Flintshire, is said to be occupied by a number of spirits, including the ghost of the notorious "Hanging Judge Jeffreys".
Members of the Cheshire Paranormal Society have held regular vigils there and claimed several sightings.
Some mediums are even said to have fled the 17th century Jacobean house because they are so unnerved.
The owner of the house has decided to throw it open because it needs restoration work - although what its spooky long-term inhabitants make of the influx of visitors remains to be seen.
Antique dealer and interior designer Cornelia Bayley bought Plas Teg Hall nearly 20 years ago.
The three storey Grade One listed building has been restored but Ms Bayley needs to increase her revenue to complete the refurbishment.
With this in mind, she decided to open her home to the public every Sunday.
If day trippers are lucky - or perhaps unlucky - they might encounter the spirit of one of its former residents who dispensed stern justice more than 300 years ago.
Plas Teg was built in 1610 by John Trevor
"Hanging Judge Jeffreys" was born not far away, in Acton Park, Wrexham, in 1648.
He gained his nickname because of the punishment he handed out at the trials of the supporters of the Duke of Monmouth.
In 1688 when James II fled the country, Jeffreys was placed in the Tower of London for his own safety.
He died there the following year at 44 of kidney disease.
One medium, Carl Fletcher, took part in a vigil at the house and claimed to have encountered several spirits.
He told the BBC Wales website: "I was gazing across this large room stood with my right hand on a settee back, looking at a newly lit wood fire.
"My hand went ice cold, I could 'see' a child, almost as Alice in the famous Wonderland books; blonde curly hair and smock-type dress with deep frills to cuffs and hem."
John Millington, chairman of Cheshire Paranormal Society said there had been a number of sightings in the hall.
"It's very active and it has been for many years," said Mr Millington.
"Paranormal groups have come in here and gone, mediums have come here and ran," he said.
"We've been very successful in what we've been getting."
Another member added: "The chair started to vibrate, it felt like underground railroads underneath."
Over the past 20 years steps have been made to restore the hall to its former glory and the restoration of Plas Teg is continuing.
