Whether you’re a history enthusiast, a devoted paranormal investigator, or simply someone who loves the eerie beauty of old forts, Fort Sisseton offers a uniquely immersive experience. Step back in time… and maybe into something a little more supernatural.
The History
Origins on the Frontier
Fort Sisseton was established in 1864 during the height of the Civil War—not on a battlefield in the South, but in the then-remote reaches of Dakota Territory. Originally named Fort Wadsworth (after Brigadier General James Wadsworth), the fort was built to provide protection to settlers and travelers of the Dakota plains from potential conflicts with Native American tribes. Located near the Coteau des Prairies, the site was strategically selected for its elevation, water sources, and proximity to trails used by fur traders and the military.
The fort was renamed Fort Sisseton in 1876, in honor of the Sisseton band of the Dakota Sioux, some of whom had cooperated with the U.S. military in the area. Unlike many frontier forts, which were hurriedly made of wood and earthworks, Fort Sisseton stood out with its sturdy, locally quarried sandstone buildings—a testament to its intended longevity and importance.
Life at the Fort
At its peak, the fort housed over 125 soldiers and officers in more than 25 well-constructed buildings. It included barracks, officers’ quarters, a hospital, a granary, a guardhouse, stables, and a gunpowder magazine. Life at Fort Sisseton was a blend of military routine and rural hardship. Soldiers conducted patrols, drilled for hours on the parade ground, and endured the harsh winters of the Northern Plains. Yet they also enjoyed social events, theatrical performances, and a sense of fraternity in an otherwise isolated post.
Much of their time was spent improving infrastructure, maintaining livestock, and occasionally confronting tensions between the U.S. government and local Indigenous peoples. The Dakota War of 1862 had recently unsettled the region, and relations remained tense for many years.
Abandonment and Rediscovery
Fort Sisseton was decommissioned in 1889 as railroads and growing settlements lessened the need for military protection in the area. After the army’s departure, the fort quickly slipped into obscurity. The once-busy compound became little more than a ghost of its former self—abandoned buildings standing silent against the prairie wind.
Local farmers repurposed some of the buildings and land over the years, but many structures deteriorated. Fortunately, preservation efforts in the 20th century brought renewed attention to Fort Sisseton. In 1959, it was designated a state historical site, and restoration work began in earnest. Today, it remains one of the best-preserved frontier forts in the United States.
Visitors can walk through barracks reconstructed down to detail, peek inside officers’ homes adorned with antiques from the fort’s active period, and explore the very foundations that supported the reach of the American government into the western territories.
The Haunt
With over 150 years of history rooted in military routines, isolation, and brushes with frontier conflict, it comes as no surprise that Fort Sisseton has stirred up its share of ghost stories. Paranormal enthusiasts and local storytellers alike suggest that the spirits of long-departed soldiers and others may still linger among the cracked stone walls and whispering prairie winds.
Ghostly Soldiers and Apparitions
One of the most commonly reported paranormal occurrences at Fort Sisseton is the apparition of a soldier walking the perimeter near the old guardhouse. Witnesses have described a figure in a long, dark coat, pacing with military precision before vanishing into the night air. During overnight stays and after-hours investigations, both guests and rangers have claimed to hear boots scraping across wooden floors—most notably in the old officer’s quarters and the non-commissioned officers’ barracks.
The Echoes of the Hospital
Perhaps the most active building for ghost hunters is the fort’s hospital. This stone building once bore witness to ailments, injuries, and even death, despite the best efforts of the medical staff stationed here. Visitors have reported cold drafts, unexplained shadows darting across the walls, and the sound of soft coughing or moaning—even when the building was empty. Sensitive visitors often exit the hospital with sudden headaches or a heavy, pressing feeling in the chest area. During EVP (Electronic Voice Phenomenon) sessions, ghost hunters have captured murmured voices, including one faintly whispering “help me.”
Unseen Forces in the Magazine
The powder magazine, built to house explosives and valuable weaponry, is another hot spot for strange energy. Despite being a simple, windowless building meant for storage, the magazine seems to carry an ambient tension. Paranormal researchers report sudden battery drains, flickering flashlights despite fresh batteries, and the inexplicable sensation of being watched. Some believe that residual energy from years of volatility—and perhaps a few undisclosed accidents—may linger among its stone walls.
EVPs and Investigations
Multiple teams of paranormal investigators have visited Fort Sisseton in the last two decades. During overnight investigations, many have walked away with spine-tingling evidence: responses through spirit boxes, photographic anomalies, and unexplainable audio. One evidence clip from a regional paranormal group (shared during the annual Fort Sisseton Historical Festival) featured the clear sound of military commands being shouted—at 3 a.m., with no one else on the parade ground.
Whether these are residual hauntings or intelligent spirits trying to communicate, Fort Sisseton leaves an undeniable impression on those sensitive to the unseen. Visitors often report that, more than eerie happenings, there’s a poignant feeling—one of history pressing in around you, full of the lives, struggles, and stories of those who came before.
