Kelley Mansion

Butte National Historic Landmark District

A large circular portico with surrounding Ionic columns dominates the facade of this grand residence, constructed in 1906 for Cornelius “Con” Kelley and his wife Mary for the then princely sum of $20,000. Butte architect W.A. O'Brien's design for the Neoclassical Revival home also features a wraparound porch supported by Ionic columns and topped with a decorative balustrade. Other detailing includes semi-circular and angled bay windows and repeating cornice brackets at the soffits. Con Kelley became president of the Anaconda Copper Mining Company and relocated to New York City in 1918, but in 1906 he worked for the Company as an attorney. He fought some of the Company’s most famous legal battles, including defending it against Augustus Heinze’s attempt to claim its copper as his own at the turn of the century. J. Bruce Kremer and his wife Cornelia lived here until 1933. Kremer was an attorney and chairman of the Democratic National Committee and presided over the Democratic Convention in San Francisco in 1920. Dan Kelly, ACM president of western operations, and his wife, Helen, lived in the home until the 1950s.
