History

Polk County Court House

Polk County was formed on January 13, 1846. It was named after President James K. Polk.

The first courthouse, a two-story structure, was built in 1846. Construction of a second courthouse was begun in 1858. Due to construction delays and the onset of the Civil War, the structure was not completed until 1866. The present courthouse was erected in 1900 in the Neo-Renaissance style. It was dedicated on October 31, 1906. In 1962, an extensive renovation was undertaken.[3]
