Billings has always held its secrets behind locked doors and forgotten staircases — and a landmark self-guided history tour recently gave residents a rare chance to step inside.

The event, known as Explore Montana: Hidden Billings, brought together history enthusiasts from across the region for one of the most ambitious historic building tours the city has ever seen.

Organized through a partnership between Preserve Montana and the Western Heritage Center, the tour unlocked twelve private and rarely accessed properties scattered throughout Billings.

These were not the kinds of places you stumble into on a Saturday afternoon.

Stops included the storied Babcock building, the Billings mausoleum, the L and L building, and the Yukon building — each carrying layers of history that most locals had never personally encountered.

Participants moved through the city at their own pace, with the flexibility of a true self-guided history tour while still enjoying curated access to spaces well beyond the usual public reach.

The Western Heritage Center also opened its own archive, collection space, and historic tower to the public for the first time in years — a moment that organizers described as genuinely rare.

Getting the event off the ground took nearly ten months of planning, close to forty volunteers, and a level of community coordination that few local history projects have matched.

Around 225 ticketed participants showed up, with additional attendees purchasing spots at the door, signaling a hunger for this kind of immersive, place-based experience.

The timing was no coincidence — the tour ran alongside the annual Montana History Conference, drawing an audience already primed for deep dives into the state's past.

Attendees traveled from across Montana to take part, with some families making the trip specifically to combine the conference with Hidden Billings hidden historic spaces they'd long been curious about.

The event arrives at a moment when Billings is actively reckoning with its architectural legacy.

Downtown, the historic Masonic Temple is currently undergoing a full restoration and redevelopment, with plans to bring retail, housing, and community office space back into one of the city's most recognizable old structures.

The renovation of Billings City Hall — originally built as a federal courthouse — recently earned a statewide award for historic preservation excellence, reflecting a broader civic commitment to honoring the built environment.

Against that backdrop, Hidden Billings felt less like a one-day event and more like a cultural statement.

For organizers, unlocking these hidden historic spaces was never just about architecture — it was about reminding a community who it is and where it came from.

Preserve Montana, which has run similar tours in the state capital for years, called the Billings debut a success and signaled enthusiasm for expanding the program to more communities statewide.

If this first edition is any measure, Billings may have just found a new annual tradition worth building on.
