I first wanted to say, the Arthur Brisbane Children's "Treatment Center" is and awful place, their are many stories online from patients their with details of abuse from the staff, thank god this place is now abandoned. It opened in 1947 and was finally closed in 2005. The building was built with the "cottage" plan, which was a smaller Kirkbride plan. It was originally made for U.S military veterans, but the State Board of Control requested for it to become a psychiatric residential treatment of children. The first building was a mansion, but later in 1972 a larger school building was built. In 1986, a litigation was filed, claiming that their was physical and mental abuse at psychiatric hospitals across New Jersey. It also claimed that the patients were stuffed into small over crowded buildings, and were barely ever let go outside to get fresh air. In 1989 the Brisbane Center had a evaluation, Staff intimidated and bullied patients, and when they would get upset about it, they would punish them. Some children had injuries from improperly implemented and outdated restraint devices and methods. The school, was mean't to hold 40 children, but held 80 children, There was no infirmary on the campus, only dormitories and a school. The start of the end of the treatment center, is when Kelly Young was killed by one of the staff. After a phone call, Kelly became very upset, after the staff said she couldn't have another phone call, she got even more upset. Kelly was in a room with a male social worker that was much bigger then her. She wasn't following his directions, and was in a emotional frenzy. Instead of approaching it with with a non violent solution, like he was supposed to do, he grabbed her and put her in a restraint called a "Basket Hold". He then forced her to the ground and dragged her to a chair. During the whole thing, she was still in a emotional frenzy, and was struggling to breath. Another social worker came and helped Williams restrain her, she lost so much oxygen that she began to turn blue. Then the Brisbane center lied to the family, claiming she had "choked on an object". Williams was fired only months later.

I think it's very easy to access this building. I've never heard of any security, or anyone be caught while exploring. I think some buildings are boarded up but you are still able to get in.
I would rate this a 4.5, because its unknown by many people and has not been vandalized that much yet. Their is not much left to see or explore. If you were looking for a place to do a ouija board or talk to spirits, this would be a good place to do it.
