The Mohawk Valley Psychiatric Center opened the doors to the historic 'Old Main' building last night to give the public a glimpse into the history of the building.

Mike Bosak of the Landmarks Society of Greater Utica says the history, the fact that its been closed and the idea that the building may be haunted is a big draw for the public.

The Old Main opened in 1843 as the first psychiatric center built in New York State for the public treatment of the mentally ill.

Bosak said in its day, the Old Main was on the cutting edge of psychiatric treatment.

After just an hour of being open, at least 1,000 visitors had already taken the tour, with a line out the door around the building.
