To spot the Dumas Brothel, just look for the bold red, two-story brick building with tall iron-barred windows and a small entrance stoop-right here on Mercury Street, standing out from its pale neighbors.
Welcome to one of Butte’s most notorious landmarks-and probably the only place in town where the phrase “red light district” comes with a historical tour! The Dumas Brothel, founded in 1890 by two French-Canadian brothers, Joseph and Arthur Nadeau, has seen more wild nights and tight-lipped days than most museums could ever dream of.
Picture this street in the late 1800s: the city was booming, the copper mines roaring, and miners poured into town, pockets heavy with fresh wages and spirits high. The Dumas Brothel quickly became the centerpiece of Mercury Street, right in the thick of Butte’s “twilight zone.” Back then, East Galena and Mercury Street were lined with dance halls, saloons, and gambling houses, a real-life Wild West backdrop.
You’re gazing at what was once the classiest-and definitely the most infamous-brothel in Butte, called the Dumas after Joseph’s wife, Delia Nadeau, née Dumas. Its bright facade housed more than just secrets; it saw decades of miners, politicians, and lovers slip through those doors. Brothels weren’t just tolerated here, they contributed good money to the city, paying the police five-dollar “fines” so often, you’d think it was a membership fee. Even mayors and senators, like Lee Mantle, had a stake in the brothel business.
By 1903, the Dumas was thriving so much, they had to dig out a whole basement of “cribs”-tiny rooms for quick visits-connected by tunnels to Butte’s business corridor. Some clients arrived through the infamous Venus Alley behind the building, others snuck in directly from the sidewalk via stairs. Inside, working girls leaned out of their windows in “varying degrees of undress,” calling out to passing miners. Newspaper reports called it “abandon that has no trace of modesty”-basically, don’t expect to hear shy voices in the archives!
Even reformers tried to clean up the area with new ordinances requiring longer skirts and “no indecent exposures,” but all that resulted in was “long dresses and long faces,” as grumbled in the local paper. Police, meanwhile, were a little less concerned with reform and a little more interested in their cut.
Through crackdowns, World War I, Prohibition, and even a government order to shut all brothels in the 1940s, the Dumas kept its doors open-now disguised as a boarding house with a secret steel door, code words, and a “peek-and-you’re-in” policy. By the 1950s, services cost five bucks, and after a bit of tragedy involving madams and star-crossed lovers, the place ended up in Ruby Garrett’s hands. She famously paid off the cops monthly and kept the place going until 1982, making the Dumas the longest-running brothel in America-a true 92-year streak. If only loyalty cards had been a thing!
When it finally shut down, the brothel changed hands: first as a museum, then an antiques shop, and now it’s being slowly restored. The Dumas is open for tours-every other Saturday, paranormal investigations included. Some say the ghost of Elinore Knott, one of its most memorable madams, never left. Guests report cold spots and mysterious footsteps in those infamous tunnels. Maybe she’s making sure no one cuts corners on the renovation!
So, whether you’re into Victorian architecture, scandalous history, or just want a souvenir from arguably the naughtiest museum in Montana, the Dumas is open for curiosity-and maybe a ghost story or two. I wouldn’t recommend leaning out the windows, though; you might end up in someone’s future audio tour!
