Circleville, Ohio is under construction. The website, that is, not the town.
From: The Dreisbach Book, page 43
Daniel Dreisbach, born in 1778, a grandson of immigrant Martin, grew up in Buffalo Valley, Pennsylvania, and married there. Before he was thirty he had moved to Pickaway Co., Ohio, had laid out a town, Livingston, no longer extant, and had built a mill on Scippo Creek. At age 32 he was appointed Director of Commissioners and given the task of establishing a County Seat for Pickaway County. The site chosen comprised a prehistoric Indian earthworks. Daniel preserved the circular plan of the earthworks, surveyed and laid out the town, and proceeded to the sale of lots, all in a few months' time in the summer of 1810. The town was called Circleville.
After a quarter of a century, the citizenry grew dissatisfied with this unusual plan of radiating streets. In 1838, with the approval of Ohio's General Assembly, the center of Circleville was leveled and new streets were laid out in a grid pattern. Now a once unique town was brought in line with all the other nearby towns. Daniel Dreisbach, still a Director of Circleville, was given the task of remaking the center of the town. The man who had traced the circle, now squared it.
