This earthwork is located about one mile east of Mound City Group on a terrace east of the Scioto River. The 292-acre site consists of a square enclosure about 900 feet on a side that is joined to a circle with a diameter of about 1,050 feet. Smaller circular structures also join the square at various points, and linear parallel earthworks extend westward toward the river for about 2,100 feet from the northwest corner of the square.
A description from 1848 indicates that the circle and square walls were 50 feet wide at the base. At that time the walls enclosing the square were 12 feet high. Continued cultivation since then has reduced the earthworks to less than 5 feet in height in most places, and the small circles and parallel walls are no longer visible.
This site is now accessible for visitors during daylight hours. Hopeton Earthworks has a 1.1 mile trail (round trip) that leads to an overlook area for viewing the earthwork remnants. The parking area at the trailhead is located next to the parking area on Hopetown road, about 1/3 mile west of North Bridge Street (S.R. 159).
