The men have been busy replacing parts of the iron roof and repairing the slate to make the 120-year-old Victorian mansion watertight.

But it's the interior that has had them buzzing after they stumbled on a hangman's noose dangling from the home's steeple roof.

Studley Park House the centrepiece of Camden Golf Course has long been regarded as one of Camden's most haunted abodes.

The haunting theories were spawned by several tragic incidents that occurred on the site like the drowning of a 14-year-old boy in the property's dam in 1909 and the death in 1939 of the son of then-owner Arthur Gregory, a sales manager for Twentieth Century Fox Australia. Mr Gregory's son reportedly died in the home's theatrette from appendicitis.

Rod Nash, director of Affordable Roofing, the company repairing the roof, said he had no doubt the house was haunted. Despite uncovering the hangman's noose, Mr Nash said he was keen to visit the house at night.

Studley Park House was built by Narellan grazier William Payne in 1889 for his bride but after running into debt he sold it to an architect.

The grand home changed owners several times over the years and has been used as a private residence, as Camden Grammar School and for army training during World War II.

Camden Historical Society's Ray Herbert researched Studley Park's long and interesting history.

``I've been in the house at all hours of the day and night and I haven't seen a ghost,'' he said.

The same can't be said for the four contestants who spent time isolated in the dormitory, cellar, theatre and tower for the 2001 filming of Scream Test, a psychological reality game show. The brave participants were locked in the house as cameras filmed their feelings, thoughts and any paranormal occurrences.

One of the contestants, who reported hearing voices, was too spooked to continue the challenge and another said he'd heard a baby crying from a corner of the room. ``Kids have said they've walked past the house and seen a lady looking out the window,'' Mr Herbert said.

``Someone once reported seeing the lights on in a part of the house where there were no lights. Another time when the fire brigade was called to investigate a report of lights being on, they checked the mains and found they were switched off.''
