San Haven Sanatorium

San Haven was built in 1912 as a tuberculosis sanatorium in the Turtle Mountains near Dunseith, and from the late 1940s served as a home for people with developmental disabilities until it closed in December 1987. At least a thousand people died there, many buried in unmarked graves on the grounds, and care in later years is remembered as poor. The Ghost Adventures crew investigated it in an episode called Dakota's Sanatorium of Death, and visitors from outside report faces in the windows and the sound of crying babies. The property has been owned since the 1990s by Chippewa owners, and the abandoned buildings are unsafe. The people who lived and died here deserve to be remembered with respect.
