In 1854 James C. Mitchell bought the site and founded Florence, which was incorporated two years later. The town was an important stocking point for settlers heading west on the California Trail. The early town included banks, a post office, a large mill, several bars, and other important businesses. Today the Bank of Florence is recognized as the oldest building in Omaha. Brigham Young was believed to have helped build the Florence Mill. Annexed by Omaha in 1917, the community is at the far north end of North Omaha.
