AMHI meaning in Medical ?

The Maine Insane Hospital, later the Augusta Mental Health Institute, was a psychiatric hospital in Augusta, Maine. It was the principal facility for the care and treatment of Maine's mentally ill from 1840 to 2004, and its surviving buildings represent the oldest surviving complex of mental care facilities in the United States. The complex is located on the east bank of the Kennebec River, immediately south of the former Kennebec Arsenal, and now primarily houses state offices. The hospital was replaced by the Riverview Psychiatric Center in 2004, located just to the south. The hospital's core complex was listed on the National Register of Historic Places in 1982, with the listing enlarged to encompass the entire campus in 2001.
