Campus Martius, a civilian stockade built in 1788, is the first organized American settlement in the Northwest Territory. See the Ohio Company Land Office, the oldest extant building in Ohio, and the Rufus Putnam House, once part of the Campus Martius stockade. Exhibits trace the early settlement of Ohio and later migrations of rural Ohioans to cities and industrial centers.
