The oldest bank in Ohio, the Bank of Marietta, first conducted business in the home of David Putnam at 519 Fort Street. Construction on the Federal style house was completed in 1805 with stone from nearby Harmar Hill. David Putnam was an active community member, director of Muskingum Academy and head of the Society for the Promotion of Good Morals during the Temperance Movement. The house remained a private residence through the 1980s. It now serves as an office building.
