Est. 1882 · Steamboat-Era Landmark · Montana's Oldest Operating Hotel · National Register of Historic Places (1976)
The Grand Union opened on November 2, 1882, at the peak of Fort Benton's run as the inland port where Missouri River steamboats unloaded freight bound across the Northwest. Designed in a Victorian style and built of brick, it was billed as the finest hotel between St. Louis and Seattle, and its opening drew hundreds of guests in what was described as the largest celebration the town and territory had yet seen.
Fort Benton's fortunes turned when railroads replaced the steamboat trade, and the hotel's prospects fell with the town's. The building endured Prohibition, the Great Depression, and long stretches of deterioration. By the mid-20th century it was in poor condition.
The Grand Union was added to the National Register of Historic Places on January 2, 1976. In the 1990s, owners James and Cheryl Gagnon undertook a multi-year restoration and reopened the hotel in 1999. It has changed hands since, most recently in 2022, and continues to operate as a restored historic hotel with a public restaurant. It remains Montana's oldest operating hotel.
Sources
The Grand Union's best-known legend is the Staircase Shooter. As the story goes, a drunken cowboy took a dare to ride his horse up the grand staircase and was shot partway up by an armed guard. Guests have since reported the sound of hoofbeats moving up and down the stairs, and sometimes lively music drifting from the direction of the old saloon.
A second figure, a spirit some staff and guests call Agnes, is said to have died in the hotel in the late 1800s; she is associated with a woman's voice and sudden cold spots in particular areas. Reports also include a woman in white seen on or near the grand staircase, and accounts of guests watching unexplained blue lights through the night.
Local television, including KRTV, has covered the hotel's haunted reputation around Halloween, and it appears on regional lists of Montana's most haunted hotels. The hotel leans into the reputation lightly rather than running a dedicated ghost-hunt program, and most of the stories cluster around the lobby and the grand staircase.

Austin, TX
Colonel Jesse Lincoln Driskill, a Tennessee-born cattle baron who supplied beef to the Confederate Army and later the Texas Rangers, opened The Driskill Hotel on December 20, 1886. Its first event, two weeks after opening, was the inaugural ball for Texas Governor Sul Ross. Driskill sold the hotel in 1888 after severe drought devastated his cattle herds and died in 1890. The hotel has hosted every Texas governor's inaugural ball since 1887.

Chico Hot Springs opened in 1900 when Bill and Percie Knowles built a hotel around a natural hot spring in Montana's Paradise Valley, already known to Native peoples and used commercially by miners since the 1870s. After Bill's death in 1910, Percie ran the property and turned it into a health-spa destination with visiting physician Dr. George Townsend before her own decline in the 1930s.
Kingman, AZ
Built in 1907–1909 by businessmen John Mulligan and J.W. Thompson, the Brunswick Hotel was the first three-story building in Mohave County and the tallest structure between Albuquerque and San Bernardino. Constructed of locally quarried tufa stone, it offered Waterford crystal stemware and solid brass beds. A business dispute in 1912 split the building in two with a dividing wall; the halves were reunited in the 1960s. The hotel is listed on the National Register of Historic Places as a contributing structure in the Kingman Commercial Historic District.
