The Bank of Washburn is a unique variation of the Romanesque Revival Style designed by architects Conover & Porter of Ashland, Wisconsin. Built in less than one year, the building was fashioned from brownstone quarried at Houghton Point north of Washburn. The bank was founded by A.C. Probert, one of Washburn's most colorful characters, who also served as chairman of the town but was ultimately convicted of embezzlement and sentenced to the Waupan Penitentiary. It was designated a local landmark in 2006.
