Quadranaou Park

The Marietta Earthworks is an archaeological site located at the confluence of the Muskingum and Ohio Rivers in Washington County, Ohio, United States. Most of this Hopewellian complex of earthworks is now covered by the modern city of Marietta. Archaeologists have dated the ceremonial site's construction to approximately 100 BCE to 500 CE. Early European American settlers gave the structures Latin names. The complex includes the Sacra Via (meaning "sacred way"), three walled enclosures, the Quadranaou, Capitolium (meaning "capital") and at least two other additional platform mounds, and the Conus burial mound and its accompanying ditch and embankment. The three acre area where Quadranaou Mound is located is believed to have been built by the Hopewell culture around 900 AD. While the mound's original use was for ceremonies performed by the Hopewell people, it and the Sacra Via was used during the Civil War as Camp Tupper. To read more about this, visit our Sacra Via page. The OES did conduct EMF readings while visiting Quadranaou Mound, finding slightly abnormal readings near the south side of the mound near what appeared to be a ramp. Could the reading have been a Native American or perhaps a wandering soldier? We will never know for certain.
