Campus Martius Museum

The Campus Martius Museum highlights migration in Ohio's history. The museum is on the site of the fortification built by the Ohio Company of Associates, as their headquarters, in 1788 when they founded the first organized American settlement in the Northwest Territory. The restored Rufus Putnam house, part of the original fort, is now enclosed within a wing of the museum. Behind the museum is the Ohio Company's Land Office.
