The Unionville community is rich in history. At one time, Unionville had a population more than double that of Cleveland. Many of the homes originally built in the early 1800's are still occupied today. A stroll through the neighborhood will reveal many Century Home plaques.

The Old Tavern in Unionville was a stagecoach stop on the Underground Railroad for hundreds of runaway slaves traveling to Canada. They would enter the tunnels in the area of the cemetery, and travel to the larger cellar tunnel under the Old Tavern. There the slaves would be fed and allowed to rest until a wagon came to take them to the Madison Docks to board boats bound for Canada and freedom.
