Have you ever heard of St. Vincent's insane asylum in Oklahoma City, Oklahoma? If not it's one of the all-time creepiest, allegedly haunted, and nightmarish abandoned places in the entire Sooner State.

This place is legendary for its paranormal and even supernatural activity. It was originally opened back in 1945 as a mental hospital that dealt with and treated adult men with extreme mental health issues.

At one time a religious order was in charge of the asylum called the Brothers of Mercy. Don't let the name fool you they were anything but merciful. The staff and doctors at the hospital were abusing, torturing, and even killing patients. One story tells of a nurse who suffocated 2 patients, murdering them.

Unfortunately, this place has a terrible and terrifying past that's filled with all kinds of mistreatment and sadly the deaths of several patients who were in the care of doctors and nurses at St. Vincent's mental hospital.

It was closed down eventually and St. Vincent's mental hospital was then turned into a drug rehab/treatment facility a few years after that. It was reportedly overseen and operated by a priest named Frank Dolan.

His story isn't a pleasant one. He was murdered by the patients he was trying to help. After such a tortured past and with everything that had happened there it was closed down permanently sometime in the 1980s.
