Fort Ancient is a Native American earthworks complex located in Washington Township, Warren County, Ohio, along the eastern shore of the Little Miami River about seven miles (11 km) southeast of Lebanon on State Route 350. The site is the largest prehistoric hilltop enclosure in the United States with three and one-half miles (18,000 ft) of walls in a 100-acre (0.40 km2) complex. Built by the Hopewell culture, who lived in the area from the 200 BC to AD 400, the site is situated on a wooded bluff 270 feet (82 m) above the Little Miami. It is the namesake of a culture known as Fort Ancient who lived near the complex long after it was constructed.

The Conrad Mound Archeological Site is an archaeological site in the southwestern part of the U.S. state of Ohio. Located east of Cleves in Hamilton County, the site is centered on an isolated Native American mound. Its location atop a ridgeline has been interpreted as evidence that the mound was constructed by the Adena culture. No artifacts have been found at the site, for no archaeological excavation has ever been carried out; however, experience with other sites has led archaeologists to surmise that the mound is surrounded by a larger zone of archaeological interest. Because of its potential archaeological value, the mound was listed on the National Register of Historic Places in 1975.

The Lake Ridge Island Mounds are a group of small hills in Logan County, Ohio, United States that have been thought to be Native American mounds. Located in an area of about 5 acres (2.0 ha) at the northern end on Lake Ridge Island in Indian Lake, the mounds are near the village of Russells Point in the southeastern corner of Stokes Township. State Route 368 passes a short distance to the east of the mounds, even weaving at one point to avoid them. The four mounds on the island are small, not reaching a height greater than 3 feet (0.91 m) or a diameter greater than 40 feet (12 m); they are small enough that they appear to be natural knolls. A report produced in the 1970s observed that the mounds were in "excellent" condition at the time, never having been disturbed by artifact seekers.

The Beam Farm Woodland Archaeological District is a group of archaeological sites in the southwestern part of the U.S. state of Ohio. Located at 3983 Stone Road near the village of Sabina in Clinton County, the district is composed of one Native American mound and two other archaeological sites spread out over an area of 2 acres (0.81 ha). Known as the Beam Farm Mound and the Beam Sites 9 and 12, the sites that compose the district have yielded artifacts from the Adena culture and the Hopewell tradition, both of which inhabited southwestern Ohio during the Woodland period. Because both the Adena and the Hopewell lived around the mound, and because both cultures built mounds, the identity of the people who constructed the Beam Farm Mound cannot be established; all that can be known with reasonable certainty is that it was raised during the early or middle portion of the Woodland period, or between 800 BC and AD 500.
