Upper Arlington is a city in Franklin County, Ohio, United States, on the northwest side of the Columbus metropolitan area. As of 2010, the population was estimated to be 33,771.
The land on which present-day Upper Arlington sits was first known to be inhabited by the Adena people, renowned for building conical mounds for burial sites. Centuries later the Wyandot lived there, eventually being expelled after the U.S. Government gave land grants to Revolutionary War soldiers in lieu of pay. Property originally bestowed in this area to Elijah Backus, Jonathan Dayton and Andrew Marker was sold as farm property to a number of different families in the 1800s.
Brothers and real estate developers King and Ben Thompson founded Upper Arlington. They purchased the original 840 acres of land, south of present-day Lane Avenue, from James T. Miller in 1913. It was directly adjacent to the Marble Cliff Quarry Co. They first referred to the area as the "Country Club District" modeled after the Country Club development in Kansas City, but by 1917 the community had become known as "Upper Arlington" in reference to its southern neighbor of Arlington (now known as Marble Cliff). The Upper Arlington Company was incorporated that year and by 1920 operated out of a field office built in Miller Park; that building also served as a streetcar shelter house and is presently the Miller Park branch of the Upper Arlington Library.
