Plain City was founded in 1818 by a man named Isaac Bigelow; according to legend, Bigelow is said to have traveled to Plain City on foot from Center County, Pennsylvania. He originally came here to make a payment for land his father purchased from his uncle, who consequently had the same name, but decided to stay and put down his roots.

Plain City sits between two of Ohio’s counties, Madison and Union, that runs along Big Darby Creek. However, before 1800, the land was predominantly used as prime hunting grounds and was occupied by the Wyandot and Mingo Indian tribes.

In the 1920s, Plain City evolved into a significant railroad shipping point for livestock, which went through the center of town and down Railroad Street, which is now known as Maple Street.

Today, Plain City’s main attraction is the Pastime Park. It is a popular spot where friends and families get together for camping and disc golf. The park also offers an extensive outdoor area suitable to house with RVs, go tent camping, hiking trail, walking paths, plus so much more. Local dining includes the Grainery on Main Street and two of the state’s best pizza joints, Jan & Tony’s Pizza and the Plain City Lanes & Pizza.
