Polk County Courthouse (Iowa)

Polk County built its first courthouse in 1847 for $2,015.[2] The brick building measured 52 by 26 feet (15.8 by 7.9 m).[2] It was located to the south of the present building.[3] After the second courthouse was completed, this first building was sold to a church for $800.[4] It later became the Union Depot serving the Wabash and the Des Moines Union Railroads. The second courthouse was built in 1858 for $94,000. The two-story Italianate structure, designed by J.C. Farrand, featured a dome. The building measured 102 by 66 feet (31 by 20 m) and the dome rose to a height of 87 feet (27 m).[4] This building was enlarged in 1866.

The present courthouse was built in 1906 on the same square as the previous courthouse. It was built for $750,000 in the Beaux-Arts style.[2] Measuring 242 by 132 feet (74 by 40 m), the rectangular structure was designed by the Des Moines architectural firm of Proudfoot & Bird.[3] It is one of the largest county courthouses in the state, and one of the most architecturally significant.[3]

The courthouse is a four-story structure composed of Grey Canyon Sandstone. In the center is a projecting loggia with three arches on the first story and eight Corinthian columns rising from the third floor to the top of the fourth floor. Projecting pavilions are located on each corner. A tall three-stage square clock tower capped with cupola rises from the center of the building. The interior features a large stained glass domed rotunda, marble columns, and murals by Charles A. Cummings and Edward Simmons.[2][3]
