City Trust is a small credit union that has sat by the shore of lake Mantino since 1987. It's about an hour south of Chicago, and is basically the corner of a strip mall. It's built on the land where Mantino Mental Hospital used to be, the location of “the Mantino Madness” in 1939 -almost 400 patients came down with Typhoid fever, and at least 100 patients ended up dying. The hospital had nearly 6000 patients, and a staff of 760.

In Episode 101, it is where Dr. Emily Dumont conducts a paranormal investigation with Donnie, Tina, Alex Reagan, and Nic Silver.
