Mound Cemetery at Fifth and Scammel Streets
Capitoleum at 615 Fifth Street
Quadranaou at Third and Sacra Via Streets
Marietta's Earthworks date from the Hopewell period (approximately 100 B.C. to 500 A.D.). They were ceremonial centers which included symbolism in their shape, location, and construction. There is no evidence that the mounds were part of urban settlements, but they seem to have been constructed and maintained by nearby family groups. Proximity to water is a common feature in Hopewell earthworks. Sacra Via Park, including the platform Quadranaou Mound at Camp Tupper, also used to include a set of parallel walls 680 feet long and 10 to 20 feet high (no longer present) extending to the Muskingum River. Capitoleum (left), a platform mound, serves as the base of the Washington County Public Library.
