Circleville, Ohio

Circleville is a city in Pickaway County, Ohio, United States, and its county seat. The city is situated along the Scioto River 25 miles (40 km) south of Columbus. The population was 13,927 at the 2020 census. Circleville is named after its original layout created in 1810, which was based upon the circular Hopewell tradition earthwork within which the city was built. This earthwork measured 1,100 ft (340 m) in diameter, and was constructed in the early centuries of the Common Era. The county courthouse was built in the center of the innermost circle. In the late 1830s, for various reasons, residents requested authorisation from the state legislature to change Circleville's layout to a standard grid format. This was accomplished by the mid-1850s. All traces of the Hopewell earthwork were destroyed, although hundreds of other monuments of its kind still remain in the Ohio Valley. By the mid-18th century, the Lenape (Delaware Indians) were pushed west from Pennsylvania by European settlers flowing into the colony.
