When I was a little girl my brother & I were so active that we, according to my mother, would drive her crazy. She would always say you're going to drive me to Chattahoochee ~ so I knew there was a mental hospital there. It scared me for years and when we drove by it I would hide. To this day it gives me a strange feeling. However staying here I ended up going over and driving around the hospital. It is huge with many many buildings and a diverse history.
The hospital was originally the site of the Apalachicola Arsenal built in the 1830s and named after the nearby Apalachicola River. The hospital's current Administration Building is the original Officers' Quarters of the Arsenal and is on the National Register of Historic Places. It served as a supply depot during the Seminole Wars. The first engagement of the American Civil War in Florida took place here on January 6, 1861 when a Confederate militia unit from Quincy overcame Union soldiers at the Arsenal.

In 1868, Florida Governor Harrison Reed made the arsenal property at Chattahoochee into Florida's first penitentiary. Florida's first recorded inmate was Calvin Williams, incarcerated in Chattahoochee in November 1868 for the crime of larceny and sentenced to one year. By 1869 there were 42 inmates and 14 guards. In 1871, the prison was put under civilian jurisdiction. Malachi Martin was appointed as warden, gaining a reputation for cruelty and corruption. He used prison labor for his personal benefit to build houses and tend his personal vineyards, amassing a huge fortune. The book, The American Siberia, was written in 1891, portraying the Chattahoochee prison as a place of relentless barbarity. The prisoners were relocated in 1876 to a prison at Raiford, Florida and the prison became a state hospital
In 1876 the prison was refurbished as Florida State Hospital for the Insane, Florida's first mental institution. The hospital has been the focus of investigations over the years for allegations of mistreatment of patients. Many of the patients are criminals who have pleaded insanity or found insane by the courts. They are evaluated there and treated so they can return to prison to serve out their sentence or go to death row.
The hospital was featured in a 1989 movie, Chattahoochee, starring Gary Oldman and Dennis Hopper

That's my story & I'm sticking to it ...It still gives me the creeps but I didn't hide this time ~ lol
Have Fun, Travel Safe & Stay Healthy!!!
