The floodwall mural project is an outdoor art gallery depicting the many centuries of Portsmouth, Ohio area history. Subjects range from the ancient mound building Adena and Hopewell cultures to historic sports figures and local notables like actor Roy Rogers, painter Clarence Carter, baseball manager Branch Rickey, writer Jesse Stuart, and actress Julia Marlowe.
The section of floodwall included in the project is 20 feet high and extends for 2,090 feet along Front Street in the historic Boneyfiddle District of downtown Portsmouth. Painting began in 1993. The murals are arranged chronologically from east to west, starting with the depiction of the Mound Builders, who are ancestors of the Shawnee Indians, and ending with murals from the contemporary era.
