Harmon's Histories: Spottswood Mansion once graced Missoula's University District
The Spottswood Mansion was built in 1891 by Edward Bonner, the lumber baron, for his daughter, Lenita. She occupied the home at 910 Gerald Avenue (which spanned the entire city block) until her death in 1959, at which time it was offered to the city of Missoula.
