The Horicon State Bank is a fine example of the Classical Revival style and is significant for the bank’s local contribution to the history of commerce in the City of Horicon as its primary financial institution for over a century.

The bank is composed of a large rectilinear red brick two story building with stone trim and details including a prominent arched entryway. The bank featured a red brick and stone façade with an interior with African mahogany and white oak interior wainscoting, furniture, and trim, terrazzo floors and bases, marble wainscoting, ornamental plaster, bronze grillwork, electrical lighting, bubblers, an elaborate set of four teller wickets, a double vault constructed of reinforced concrete with Diebold Safe Company doors, and a pair of American Banking Company ‘tamper-proof’ alarm bells.

The bank has undergone a series of renovations, additions, and restorations during its history in 1960, 1980, 1985, and 2009; though none of these has significantly detracted from the building’s integrity or character.

Designed by architect Herman W. Buemming of Milwaukee, the bank was promoted as the grandest and most expensive commercial building in Horicon when it was built and is now one of Dodge County’s most architecturally intact and significant commercial buildings.
