Hennessy Building

Butte National Historic Landmark District

In little more than a decade, entrepreneur Daniel Hennessy’s mercantile business became Montana’s first and most elegant department store. Minneapolis architect Frederick Kees designed the magnificent 1898 Renaissance Revival style showcase of steel, terra cotta, decorative glass, and wrought iron grille work to house Hennessy’s thriving business. The Anaconda Copper Mining Company added to the building’s prestige, moving its executive offices to the sixth floor in 1901. There the company reigned over its empire atop the city’s most modern building. Façade restoration in 1989 by ENTECH, Incorporated, rejuvenated the building, which now serves as a major business center accommodating modern offices.
