Liberty Memorial Building — the haunted statehouse annex of Bismarck, North Dakota

The Liberty Memorial Building in Bismarck, North Dakota, was built in 1924 as an annex to the State Capitol and has served various government functions over the decades. Former employees have reported a range of paranormal phenomena, particularly when working alone in the building after hours. The most commonly described experience is the sound of footsteps in empty corridors — heavy, deliberate footfalls that seem to move from room to room. Some workers have reported seeing the figure of a man in a military uniform standing in doorways, who disappears when they approach. The building was constructed as a memorial to North Dakota's World War I veterans, and the military apparition may be connected to this commemorative purpose. Other reported phenomena include lights switching on in locked offices, the sound of a typewriter clicking in an empty room, and cold drafts that sweep through the building on still, warm days. The building's connection to wartime sacrifice and its memorial function give the hauntings a poignant quality — as though the spirits of those honored by the building have chosen to make their presence known within its walls.
