The Great Hall of The Original Montana Club

Cass Gilbert The Architect

One Hundred and Forty Years at Montana’s Finest Address

Perched atop The Original Montana Club, the Sixth Floor Banquet Hall has been the
architectural crown of Montana’s most celebrated private club for more than 140
years. Rebuilt after the great fire of 1903 and reopened in 1905, this remarkable
space was designed by renowned American architect Cass Gilbert—the visionary behind
the Minnesota State Capitol, the Woolworth Building in New York, and later the
United States Supreme Court.

After the devastating fire of 1903 destroyed much of the Club’s original building,
its members chose not simply to rebuild—they chose to create a landmark worthy of
Helena’s prosperity and ambition. They commissioned renowned American architect Cass
Gilbert, whose Beaux-Arts approach blended classical symmetry, refined
craftsmanship, and enduring elegance with the confidence of a rapidly growing
nation.

Completed in 1905, the rebuilt Montana Club reflected the optimism and
sophistication of America’s Gilded Age. Every proportion, window, cornice, and
architectural detail was designed with intention. Gilbert understood that great
architecture should elevate the people who gather within it, creating spaces that
inspire conversation, celebration, and civic life.

The sixth-floor banquet hall became the architectural crown of the building. Elevated
above the streets of Helena, it offered sweeping views of the city and surrounding
mountains while providing a setting unlike any other in Montana. Beneath its soaring
ceilings, generations of Montanans celebrated milestones, welcomed distinguished
guests, forged partnerships, and shared the conversations that helped define the
state’s civic and business history.

Gilbert would later become one of America’s most celebrated architects, designing
landmarks including the Minnesota State
Capitol
, the
Woolworth Building in New York
City
, and the United
States Supreme Court Building in Washington D.C.
,
His work at
The Original Montana Club remains one of Montana’s finest surviving examples of
Beaux-Arts
architecture
and a lasting symbol of Helena’s remarkable
Gilded Age.

Today, 1885 continues that legacy from the very room Cass Gilbert envisioned more
than a century ago. Every dinner is served within an architectural masterpiece where
exceptional cuisine, historic craftsmanship, and Montana’s rich heritage come
together high above Last Chance Gulch.
