‘Ghost hunters’ have been criticised for illegally breaking into the derelict Sunnyside Royal Hospital.
Sunnyside Royal Hospital at Hillside, by Montrose, closed its doors in December 2011 after serving as a mental health facility for 153 years in the area.
A group on Facebook called Abandoned Places and Ruins in Scotland posted 92 photographs on their social media page of the former asylum after wandering around the old wards looking for paranormal activity.
A spokesperson for NHS Tayside said: “Due to health and safety reasons, NHS Tayside will never give permission for members of the public to enter any building on the Sunnyside site.
“We take any breach of security very seriously.
“The buildings are NHS property and it is illegal to enter them without our permission.
“There are alarms in place and security services continue to patrol the site.”
The Abandoned Places and Ruins in Scotland states: “A lot of places in Scotland are abandoned and meant to be haunted as in old asylums hospitals etc we are going to a lot of different places see what we get.”
Chief Inspector David McIntosh, Local Area Commander for Angus, said: “We would remind the public that derelict buildings and properties that have fallen into disrepair, whether large or small, are not safe environments to be in.
“Whether it’s people who wrongly think such buildings serve as a playground or place to explore, or the less well-intentioned looking to steal property, the message is the same - keep out.
“Derelict buildings can be and often are very unsafe and pose a genuine danger to anyone who ventures in.
“Police officers are aware of this issue and will continue to give the area their attention.”
NHS Tayside put Sunnyside, which was Scotland’s oldest psychiatric hospital, up for sale last year.
Noteworthy patients include the father of Arthur Conan Doyle, who was a talented artist, and Shetlander sculptor Adam Christie, who made stone sculptures while he was at Sunnyside using very basic tools.
