In 1818 Coolville was platted (laid out by) by Simeon W. Cooley, for whom it is named. The village was incorporated in 1835.
By the 1830s, Coolville contained two stores, a gristmill, and a sawmill.
Coolville has been noted for its unusual place name. The village is located close to three other "hot/cold" communities: Torch and Frost (both unincorporated communities in Athens County), and Snowville in Meigs County.
"Roots" General and Feed store was built in 1846 and still stands as a remodeled home with a business front.
The bank originally was built in the late 1800s on Main St, known today as the "Village Hall".
