List of shell ring sites
This List of shell ring sites includes archaeological sites with confirmed and possible shell rings. Shell rings have been reported from Colombia, Peru, Japan, and the southeastern United States. Some sites have two or more shell rings, including some with two more or less equal rings joined together, or a main ring with smaller rings attached to it. About half of the sites with shell rings in the United States are in the Sea Islands of South Carolina, Georgia, and northeastern Florida. Colombia
