A TEAM of ghostbusters has put spooky goings-on at a Welsh castle under the spotlight.
The Phantom or Fraud project, a paranormal investigation squad, camped out at Carew Castle, in Pembrokeshire, to investigate unusual phenomena within its walls.
As well as being a popular attraction for holidaymakers, the stronghold also has a reputation for attracting visitors of a more ghostly variety.
Its celebrated spirits include:
Princess Nest, who once lived in the castle and is now said to walk its battlements at night; and
a Barbary ape implicated in the killing of 17th-century inhabitant Sir Rowland Rees.
The 14-strong paranormal team, led by former teacher Helen Livesey-Jones from Chepstow, set up hi-tech investigation equipment inside the castle to try to assess the stories.
It is the first time the group, which carries out paranormal investigations across Britain, has examined a castle in Wales and Ms Livesey-Jones is now writing a report on their findings.
"We do try and do it from a scientific point of view," she said.
"We stayed overnight until half five in the morning. I've never been so cold in my life.
"Although we have yet to look at all the findings we did get some hits."
Mike Cannaby, her partner, who is a computer technician and also a medium, said a previously unknown Frenchman was one of the pick-ups - found in one of the castle towers.
"There's definitely presences there although whether or not they are ghosts or spirits its hard to say," he said.
"We have some very interesting stuff including some interesting photographs."
The couple took an interest in Carew after taking part in a Sealed Knot event in Pembrokeshire last year. On hearing some of the castle's stories they asked if they could return with their equipment and carry out a full investigation.
Last month, armed with video and still cameras and heat sensors, they spent the night amid the ruins, aided by castle staff.
Apart from Ms Livesey- Jones, no member of the team was allowed to do any research beforehand so as not to influence their findings.
The team also split up into groups to double check results.
As well as the detection of presences, they also found a number of hot and cold spots with temperatures dropping to as low as -17C at one point.
Located on the site of an Iron Age fort, the first castle at Carew dates back to Norman times.
It was once the home of Princess Nest, known as the Helen of Wales, when she was married to Gerald de Windsor.
In later times the fortification was transformed into an Elizabethan country home.
Today the castle and home is owned by the Trollope-Bellew family - who can trace their ancestry back to Nest - but run by Pembrokeshire Coast National Park.
It attracts 34,000 visitors a year.
Castle supervisor Helen Davies said she was looking forward to seeing the completed report.
"We've had a group of dowsers in before who told us that we had around 23 spirits around the place so we knew about its reputation," she said.
"It does not really make you nervous. There's some dark areas you might want to avoid but apart from that, no."
