After 1855
The people of Mount Pulaski reused the former courthouse for various purposes. From 1857 until 1878 it served as the town school, from 1878 until 1889 it was the city hall and community center, and from 1889 until 1936 it was the town library and post office.
Illinois Governor Henry Horner launched a statewide search in the 1930s for surviving public buildings with which Lincoln had been familiar. Mount Pulaski gave the old brick courthouse building to the state of Illinois in 1936, and the state extensively restored it in 1936–1939 to resemble its function as the county courthouse.
