Cedar-Bank Works is group of Adena culture earthworks located in Ross County, Ohio in the United States.

Cedar-Bank is Adena in its design and style, and is believed to have been built before the sites at Hopewell Culture National Historical Park.

The fourth side is protected by a natural bank or bluff, 70 feet high, and so steep as to admit of no ascent, except at one point where it has been gullied by the flow of water.

They describe a four foot tall "elevated square" as "covering the northern gateway and two hundred feet interior to it."

[4] They complement the location of the pyramid and circle as having a "fine view" of the river and being "well chosen," by the builders.

They did note that they discovered "inconsiderable remains, consisting of small, low terraces, and little mounds and circles."

The men reported that there must have been some type of significance in the placement of walls, suggesting that the space was used for "celebration of certain games" or religious ceremony.

Based on casual observation, Fowke noted that the "south wall had been worn away," but it is unknown what happened.

He suggested that perhaps the river washed away the loose soil and gravel that the wall was built upon, causing it to fall apart.

[5] He cites cultivation as the source of the walls being destroyed in most areas, showing a considerable change from the time that Squier and Davis had been there in 1845.
