Could this be one of the most haunted film sets in Australia?
The Callan Park mental asylum is the scary backdrop for new horror film Ravenswood and now cast members have revealed some of the supernatural experiences they encountered while working on the Sydney-based film.
"We had a crew member refuse to come back to set. I think his exact words were 'You guys don't understand what you're dealing with,'" executive producer and actor Adam Horner recently told News Local.
Meanwhile actress Madeline Marie Dona revealed she felt uneasy filming at the abandoned asylum at night.
"I felt a real sense of eeriness. Most of our shoots were at night," she added.
In the film, a group of tourists visit the empty "Ravenswood" asylum for a ghost tour and it would seem the plot mimics real life, with the building considered one of Sydney's most haunted.
It was first established in 1873 when the New South Wales government bought the building after overcrowding at the Gladesville Hospital for the Insane became an issue.
Originally built to house the "insane population" it treated patients up until 1994.
Photographer Merve Kozak recently went inside the building to take a series of snaps, showing how rundown it has become since it closed.
With graffiti on the walls and beds and chairs left behind in the facility, Merve wrote that exploring the building isn't something they would do alone.
"Personally, having a belief in spirits myself, walking through Callan Park gave me the critters and is something I would never explore through alone," Merve wrote on the Facebook post.
"While toilets and showers echoed, the hallways didn’t. Sounds from one side of the place weren’t heard on the other side, and it was one hell of an experience to be here for a full day."
