You know, I'm fairly new to these boards, but I work in a hospital and had to check out this thread. Far be it from me to dispel the myths, but from the pics that DarkStar posted, the place just looked to me like a modern hospital that people abandoned in a hurry.
Pic 14/15 are modern lighting equipment circa 1970s
Pic 16 looks like the entrance to an operating suite complete with the "Do not enter without authorization" sign that hangs on the entrance to our operating room.
Pic 19 looks like a fairly modern waiting room
and Pic 23 looks like the elevator at a hospital which I used to work at.
Some of those pictures of broken doors and tiled walls are reminiscent of some of the operating room suites that I've been in that were built during the sixties (note the hideous color).
Here in the states, we have a few hospitals that shut down during the eighties, when the healthcare system was having trouble staying afloat. Some of those shut down in one day...the staff came in that morning, was told to ready their patients to be transferred to another facility and then go home. Most of those hospitals were operating in the red for quite sometime and one day the money just ran dry and they shut their doors that day.
In fact, we have one of those near where I live and most of the furniture, accesories, equipment and other stuff that couldn't be utilized by other facilities has just remained in place. Other than what vandals have damaged, that is. I have to say the scariest thing about those pics was what people had spray-painted on the walls and what had been damaged.
That's not to say that this Ochil Hills wasn't a mental institution or a TB sanitarium at one time or that abandoned hospitals aren't scary as hell, but it looked to me that this place was used as a regular hospital until it was abandoned.
Also, a note about the chimney: Most older institutions have incinerators like the one you all talk about. They were used to incinerate laundry that was soiled beyond use, used medical supplies, old specimens, and other hazardous waste. Since the age of AIDS, the government here has put high standards on the handling of biohazardous materials and so most of that stuff now is either totally disposable and sent to large plants that handle biohazardous waste, or, if not disposable, sent outside the hospital to be laundered and/or resterilized.
I might also add that the hospital I worked at previously had a ghost on the second floor (operating rooms and sterile supply). The hospital was built during the early 60s, and during the 1970s, a nurse working the graveyard shift hung herself from one of the lights in the surgical suite. There were some older ladies that worked in supply when I worked there and they would refuse to work after hours if they were alone. Doors would open and shut, lights came on and footsteps could be heard in the back hall. THAT was a creepy place and it was and is still a fully functioning hospital.
Anyway, I guess that's more information that you all needed, but I thought I would share...sorry I rambled on more than I thought
