The Atlanta Public Library, located at the intersection of Race and Arch Streets in Atlanta, Illinois, was built in 1908 and has operated continuously as a library since.

Architect Paul A. Moratz's design combines the Neoclassical with an octagonal plan, an uncommon mixture of styles.

The building's eight sides are all symmetrical except for the front, which is broken by a classical portico with Doric columns and a round arched entrance.

The Atlanta Museum formerly operated in the library's basement.
