Where: Brentwood, New York
Years Of Operation: 1941 to Present

Pilgrim Psychiatric Center was once the largest hospital, asylum or otherwise, in the world. But that's not what it will be remembered for. Alan Ginsberg's mother was treated for schizophrenia here, and died here in 1965, but that's not what comes to mind when one mentions Pilgrim, either.

Its legacy is built on more unsettling details, like the cruel methods Pilgrim patients endured for treatment, including shock therapy, pre-frontal lobotomies, and insulin shock therapy, which was intended to send patients into a coma. Piligrim is still operating today, though on a much smaller scale, and of course, sans the Medieval methods of treatment.
