Location:  514 West Jefferson Street / 6th Street

Built:  1938 – 1939

Style:  Art Deco

Architect:  Tourtelette & Hummel and Wayland & Fennet

Contractor:  J O Jordan & Son and Jordan Wilcomb.

 

Description:  The building  faces south and is a nine story Indiana limestone structure. The building is located on spacious landscaped grounds in the center of Boise. The base is three stories high and the central tower is nine stories. The interior has Art Deco ornamentation and murals painted by Ivan Bartlettin a vernacular style which depict the history of the Western Expansion into Idaho and are perfect examples of the depression-era frugality seen across the nation at the time. The building was a Works Progress Administration project. The building has been purchased by the State of Idaho. The building was purchased by the State of Idaho for use as legislative offices and the building was renovated. The architect is LKV Architects ( Leatham Krohn Van Ocker ).

 

Note:  The interior is simple, architecturally, but the building’s greatest asset is inside. A three floor mural was integrated into the building, because the Works Projects Administration (WPA) was as eager to hire construction workers as artists. Originally designed with each panel representing a legend in Idaho history, the artists (predominantly from outside of Idaho) painted stereotypical western farm scenes.

The second courthouse was constructed in 1938 to 1939 and is still standing. The third and present courthouse was constructed in 2000 to 2002 at a cost of $47,000,000.
