The old post office in Cairo was built during the New Deal and has the characteristic architecture of the era. While some post offices of the time were built in the Neoclassical Revival style, this one is Stripped Classical, meaning, essentially, a “flatter” interpretation of Neoclassical.

An Art Deco patriotic shield is located above the entryway.

A mural by Paul L. Gill, entitled “Products of Grady County” was originally located in the post office but is now in the Grady County History Museum, just down the street.
