Est. 1903 · Gilded Age Architecture · Montana Heritage · Henry Janeway Hardenbergh
Preston Boyd Moss arrived in Billings in 1892 and established himself as a prominent banker and businessman. By the turn of the century, he commissioned New York architect Henry Janeway Hardenbergh to design his family residence — a choice that brought one of the era's most distinguished architectural minds to Montana.
Hardenbergh completed the design in 1903. The resulting mansion is a 9,000-square-foot Richardsonian Romanesque structure with Moorish-influenced interior details, sandstone exterior work, and imported materials from Europe and Asia throughout the interior. Hardenbergh's other major commissions include the Plaza Hotel and the original Waldorf-Astoria in New York City.
The Moss family occupied the mansion for decades. A child connected to the family died in the house, a fact documented in local records and central to the mansion's paranormal reputation. The property passed through several transitions before being preserved and opened as a museum.
The Moss Mansion Museum now operates as a historic house museum with guided tours, seasonal programming, and the annual 'Haunted Moss' Halloween event, which has run for over 25 years. Ghost tours — separate from the Halloween theatrical event — are conducted by trained staff with Montana Paranormal Society findings incorporated into the tour narrative.

The Montana Paranormal Society has conducted multiple documented investigations at Moss Mansion, and their findings form the backbone of the ghost tour narrative staff present to visitors.
The billiards room is the most consistently cited location. Staff and tour guests have independently reported hearing a female voice there — distinct enough that multiple staff members investigated the source and found no one present. The identity of the figure is not established, though the mansion's history includes the death of a young girl associated with the family.
Shadow figures are reported throughout the mansion, typically in peripheral vision and in the upper-floor corridors. Cool breezes in closed rooms are a recurring report that does not align with the building's ventilation, particularly in rooms on the second floor.
The apparition of a little girl has been reported by multiple visitors over the years — a figure appearing briefly and then absent. In accounts compiled by tour staff, family members have also been described appearing together in lower-floor rooms.
Doors opening and closing without proximate cause are noted in staff accounts going back to early periods of the mansion's museum operation. The reports are consistent across staff generations, suggesting either a persistent environmental anomaly or a well-established internal narrative passed between employees.
