This city is the county seat of Pickaway County. Founded in 1810, the name is dirived from the circular portion of a large Hopewell era earthwork upon which it was built. The original town plan integrated Circleville into the preexisting land with a street layout of concentric circles. An octagonal courthouse stood directly in the center. In 1837, the Ohio General Assembly authorized the “Circleville Squaring Company” to convert it into a square. By 1856, this had been completed in several phases. No remaining traces of the original earthworks remain, though a few old buildings retain curved walls that were part of the original circular layout. As of the 2010 census, the population was just over 13,000.
It is best known for the famous festival “The Annual Circleville Pumpkin Show.” This festival is held every year on the third Wednesday thru Saturday in October. It attracts over 400,000 visitors each year.
