Fairmont City Hall is located at 100 Downtown Plaza, Fairmont, MN 56031.
The history of Fairmont can be traced back to the days before Minnesota became a state. In 1826, a fort was established which served as an army post and trade center on the site now covered by the Martin County Courthouse. The first permanent settlers were E. Banks Hall and William H. Budd. In June 1857, these men built their homes on lakes that still bear their names. Mr. Budd recorded that in January of that year, twenty men, nine women and twenty-three children lived in the Fairmont area.
Fairmont was platted in October 1857, by the Des Moines and Watonwan Land Company, by whom the name was applied. The City was named for the rolling hills which surrounded the adjacent lakes. The original name was Fair Mount, but this was later changed to Fairmont. Fairmont had the first post office in Martin County, dedicated on October 9, 1858, with William Budd as the first postmaster.
Fort Fairmont was established in 1862, shortly after the Sioux Indian Uprising which terrified settlers throughout southern Minnesota. With the end of the Civil War and subsiding of Indian troubles, Fort Fairmont was abandoned. Closely following the hard times after the Civil War, the "Grasshopper Plague" of 1873-1877 descended on the impoverished farmers, and many were forced to abandon their holdings and leave Martin County. This gloomy picture was brightened by the arrival of English colonists during the same period. They came to develop new methods of growing beans, spent their money lavishly, built a number of beautiful homes and brightened the hillsides with their scarlet foxhunting expeditions.
The Southern Minnesota Railroad was completed to Fairmont in 1878, and marked the beginning of a new period of development for the area. In 1896, the first switchboard and telephones were installed in Fairmont providing services for 35 subscribers. Electricity became available in 1890 from a privately owned plant which provided service from sun up to 10:00 p.m. The City purchased the generating plant in 1902. City water became available in 1897 from Budd Lake, but it was unfiltered. The initial filtration plant was built in 1924.
Industrial development of note began in 1909 when Fairmont Railway Motors was established to make small farm engines. These engines became useful on railway hand cars. Agriculture related industries, such as the Fairmont Canning Company and Stokely-Van Camp added to Fairmont's industrial growth.
From the mixed agriculture-industrial-based economy, Fairmont has grown and prospered into one of the state's leading rural communities. Adding to the steady growth and stability of the Fairmont economy are several leading industries which have settled in the community. Among these are: Fairmont Foods of Minnesota, Avery Weigh Tronix, Harsco Track Technologies, Hancor, 3M, Aerospace Engineering, CHS Inc., and Buffalo Lake Energy.
