Chestonia was a town that once stood near the present-day junction of M-66 and East Old State Road. The town was founded when the Detroit and Charlevoix Railroad built a station at the town site. A post office was built near the depot and continued to operate until the 1960s. Today, Chestonia is but a ghost of its former self. No structures from the original town still stand, and the railroad grade is barely noticeable through the overgrowth of trees and weeds.
