The Original Mahaska County Courthouse Site

The citizens of Mahaska County erected the first courthouse on this site in 1845. The building, a two-story wooden structure, was used not only as a courthouse but also for all manner of “frontier frolics,” including church services, operas, and, in 1849, a Native American dance. The structure was moved from this site sometime between 1867 and 1875.

In 1876, Mahaska State Savings Bank purchased the “old courthouse corner” for $6,000.00 and constructed a two-story brick building considered at the time to be a “real beauty”. The Oskaloosa Herald reported the interior appointments as follows: encaustic floor tile from England, Italian marble deposit counters and black walnut used throughout. In 1879, the bank merged into the Oskaloosa National Bank.

Business in the Iowa Building

On the evening of April 22, 1896, a fire broke out in the adjoining Green and Bentley Wholesale and Retail Drug Company building. The Oskaloosa Herald reported at the time, “the more water the firemen poured on the blaze the fiercer it seemed to burn”. The bank, built to be fireproof, withstood the flames but sustained heavy smoke and water damage. After the fire, Foster & Liebbe of Des Moines remodeled the front entry, adding a sandstone portico and “iron gates on the doors to protect against loafers.”

Barbershops also frequently occupied the lower level of the building. In 1901, Charles Sterling installed a drinking fountain in his barbershop. The Oskaloosa Herald reported that a cold glass of water from the fountain was “something of a novelty” at that time.

The Great Depression and WWII

The Great Depression caused the closing of five banks in Oskaloosa, including the Oskaloosa National Bank. The bank went into receivership, with depositors receiving only twenty-five cents on the dollar, and its last day of operation was December 31, 1931. This marked the end of a financial institution that had printed over $1,000,000.00 worth of national currency in eight different denominations throughout a period of fifty-two years. 

In 1937, Iowa Trust and Savings Bank purchased the building and began its operations. In 1943, during the midcentury modern era, the bank underwent extensive renovations, which included installing florescent lighting and a drop ceiling. During that era, the bank also removed its copper and brass grillwork and donated it to the World War II scrap metal drive. In 1959, to further the modern streamline aesthetic, the bank had a grey granite veneer installed over its exterior. Inside, it contracted with Garret Music Company to pipe in “800 different numbers of peaceful background type of music” over a phone line. The Oskaloosa Herald reported, “Complete sound installations and individual installation are offered by Garret’s ultra-modern method of background music production. With Fone Music, the need for buying records or tapes is eliminated.”

The Modern Day Iowa Building

In 1990, the bank building converted to apartments, and in 1998 it was condemned due to poor conditions. In 2008, the Oskaloosa Downtown Development LLC renovated the building, in which part of the process involved stripping the granite exterior and replacing the portico pillars original to its 1896 renovation. Chuck Russell had found the pillars in Oskaloosa resident Edwin Zimmerman’s yard, and Zimmerman gifted these to the project. The pillars are now restored and supporting the portico once again, and the Iowa Building is now available for community events throughout the year.
