The 19th- and 20th-century hospital buildings cover 300 acres, including a Civil War cemetery that serves as the final resting place for 300 Confederate and Union soldiers. The Brookings Institution suggests this might be the first public cemetery where people were buried regardless of race. The site has one of the city’s most spectacular views. The original buildings are no longer open, but visitors can tour the campus. Carl Jung, whose research on the subconscious is nearly as famous as Freud’s, worked with black patients at St. Elizabeths. He studied whether one’s unconscious was influenced at all by race; he determined that race has no effect on the subconscious.
