McLean Hospital opens.

Architect: Charles Bulfinch. Originally the Asylum for the Insane, then the Psychiatric Hospital of Massachusetts General Hospital, it is located in the former Joseph Barrell Mansion on Cobble Hill in Charlestown (now Somerville). Incorporated on February 25, 1811, it is the first hospital for the mentally ill in New England and fourth in the U.S. Rufus Wyman is the first superintendent. It is renamed the McLean Hospital for the Mentally Ill in 1892, for local merchant John McLean, who bequeathed much of his estate to the institution, and moves to a campus in Belmont, for which Frederick Law Olmsted submitted a design, in 1895. Olmsted subsequently becomes a patient there, as does Robert Lowell. The original building in Somerville is demolished in 1929.
