Portsmouth, Ohio, despite its elevated location near the Ohio River, historically suffered from severe floods. Significant flood events in 1884, 1913, and 1937 necessitated the construction of a floodwall for community protection. Following the devastating 1937 flood, city officials erected the floodwall to prevent future disasters. Residents later envisioned the floodwall as more than just a protective barrier; they desired it to become a canvas for their city's historical narratives. In 1992, a nonprofit organization was established with the express purpose of creating a mural on the floodwall. Artist Robert Dafford and his team commenced painting in 1993, creating expansive murals that span over 2,000 years of local history. These artworks are presented across 60 large panels, illustrating key aspects of Portsmouth's past. The murals cover topics such as Native American ancestry, pioneer settlement, river trade, the Underground Railroad, notable athletes, and daily life. Stretching nearly half a mile, the Portsmouth Floodwall Murals extend 2,090 feet along Front Street. The impressive 20-foot height of the floodwall provides an extensive surface for this vibrant historical outdoor gallery.
