Letchworth Village was a residential institution located in Rockland County, New York, in the hamlet of Thiells built for the physically and mentally disabled of all ages, from the newborn to the elderly. Opened in 1911, Letchworth Village at its peak consisted of over 130 buildings spread out over many acres of land. It was named for William Pryor Letchworth, who espoused reform in the treatment and care of the insane, epileptics, and poor children.
