On October 5, 1851, the Territorial Legislature of Utah passed a resolution providing for the organization and settlement of Millard County with the seat of government in the county, to be called Fillmore City, named after the President of the United Sates, Millard Fillmore. Later that month two companies of covered wagons set out to make that settlement. Within fifteen days the first building, a school, made of cottonwood logs, was completed. Anson Call, a well-known colonizer, with assistance of others, was largely responsible for settling Fillmore. The city was planned to be the Capitol of the State, and construction began on the Statehouse.The first wing of what was to be a monumental structure was completed and used for legislative sessions in 1855 and 1856. The building was never completed and the Capitol was moved to Salt Lake City. The Statehouse stands today as the oldest existing governmental building in the state.


On January 12, 1867, Fillmore was officially incorporated by the State Legislature. Since that day growth and progress have been continual. From fort, to town, to city, Fillmore has grown and developed into a fine city, providing its citizens with many services. There are approximately 2150 people residing in Fillmore.
