The McRaven House in Vicksburg, Mississippi, is widely regarded as the most haunted house in the state. The structure was built in three phases — 1797, 1836, and 1849 — giving it a unique architectural character that blends frontier, Empire, and Greek Revival styles. During the Civil War, the house served as a Confederate field hospital during the Siege of Vicksburg, and wounded soldiers died in its rooms. The owner, John Bobb, was murdered by Union soldiers in the garden in 1864 after confronting them for picking flowers from his wife's garden. His ghost is the most frequently reported apparition, seen standing in the garden near where he fell. Inside the house, visitors and tour guides have reported the apparition of a young woman in a white dress on the second-floor staircase, believed to be Mary Elizabeth Howard, who died during childbirth in the house in the 1830s. The brick-walled room where soldiers died produces reports of moaning and the smell of blood. Objects move on their own, doors slam shut, and at least one tour guide quit after being pushed by an unseen force on the staircase. The McRaven House was featured on Ghost Adventures, which recorded extensive anomalous activity during their investigation.
