Where the bodies are buried

(Image credit: The University of Mississippi Medical Center)Built in 1855, the Mississippi State Insane Hospital housed an estimated 35,000 patients over a span of 80 years, until it was shuttered in 1935. Experts suspect that as many as 7,000 of the asylum's former patients are buried in unmarked graves under what is now the University of Mississippi Medical Center (UMMC).

Respectful removal

Highly compressed

Valuable insights

High mortality

(Image credit: The University of Mississippi Medical Center)Between 1855 and 1877 alone, 1,376 patients were admitted to the Mississippi State Insane Hospital. One in five of those people died, from ailments including "softening of the brain," "nervous exhaustion" and "chronic diarrhea," according to hospital records.

Anonymous remains
