Est. 1846 · Underground Railroad Station · Civil War Field Hospital · Steamboat Era Lodging · Mormon Pioneer Craftsmanship
The Mason House Inn was constructed in 1846 in Bentonsport, a small village on the Des Moines River in Van Buren County, Iowa. Mormon craftsmen built the structure as a lodging house for the steamboat travelers who moved goods and passengers along the river during the mid-nineteenth century boom years. The building's brick construction and generous proportions reflected the traffic that Bentonsport saw before the railroads bypassed the river trade entirely.
Documented history connects the inn to the Underground Railroad — it served as a station for freedom seekers traveling north through Iowa — and to the Civil War, when it functioned as a field hospital for the region's wounded soldiers. A physician working at the makeshift hospital died in the building during this period, according to reporting by the Iowa Gazette. Three previous owners of the property also died within the building, a fact the current owners acknowledge and which contributes substantially to the inn's documented haunting reputation.
NBC's Today Show named the Mason House Inn one of America's most haunted lodgings in 2006. The current owners have operated the inn as both a bed-and-breakfast and a ghost-tourism destination, maintaining the property's nineteenth-century character and accepting overnight guests year-round.
Sources
The Mason House Inn's haunted reputation rests on a documented foundation: multiple deaths within the building across different eras. The physician who died during Civil War hospital use, three previous owners who died in the building at different points in its history, and the uncounted freedom seekers and travelers who passed through during the decades of steamboat traffic all contribute to accounts of an unusually active site.
Guests and staff report a range of phenomena: footsteps in unoccupied rooms, the sensation of a presence at bedside during night stays, unexplained sounds from the stairwells, and — in the more dramatic accounts — apparitions in period clothing in the inn's common areas. The current owners have documented some of these accounts and incorporated them into the property's identity without manufacturing the claims.
The Today Show's 2006 designation of the Mason House Inn as one of America's most haunted lodgings brought national attention that the inn has maintained. One blog source from 2012 references a claim of over 300 spirits on the property — a number the research cannot independently verify and which likely reflects the aggregate of paranormal investigators' claims rather than documented incidents.

Gettysburg, PA
Built around 1810 by tanner John F. McFarlane and expanded with an 1833 brick addition, the Farnsworth House sits on Baltimore Street in Gettysburg. During the 1863 battle, Confederate sharpshooters occupied the structure, and the south-facing wall still carries more than 100 bullet holes from Union counter-fire.
Eureka Springs, AR
The 1886 Crescent Hotel was built as a luxury Victorian resort atop the Ozark mountains of Eureka Springs, Arkansas, then briefly operated as a women's college before its most notorious chapter: Norman Baker's fraudulent cancer clinic from 1937 to 1940. Baker charged dying patients for treatments that offered no medical benefit, and the hotel retains his intact basement morgue.
Poncha Springs, CO
The Jackson Hotel—originally the Poncha Springs Hotel—was established in 1878, making it the oldest surviving building from Poncha Springs' 1880 founding. It endured fires in 1893 and 1903 and has operated continuously near the junction of US-285 and US-50 in Chaffee County.
