Campus Martius Museum, Marietta OhioCampus Martius, a civilian fortification, was built in 1788 by the Ohio Company of Associates. When the fort was disassembled, General Rufus Putnam left his blockhouse on the original fort site. In 1931 Campus Martius Museum was erected over the Rufus Putnam House. The Ohio Company Land Office, the oldest known building in Ohio, was also moved to the museum site. Today, the museum preserves the history of America's migration west, its earliest native inhabitants, and Marietta's pioneers.

Free parking is available at the rear of the museum and on-street. Campus Martius Museum's three floors of exhibits are wheelchair accessible, excluding the second floor of the Rufus Putnam House. No visit to Campus Martius is complete without a visit to the nearby Ohio River Museum.

Also consider a stop at Mound Cemetery where you can climb a conical Indian mound and view burial sites of several Revolutionary War veterans. Here are a few items to help you explore history while in Marietta:
