Less-known than the larger Native American shell ring farther south at Sea Pines [1], the Green’s Shell Enclosure (803/734-3886, daily dawn–dusk) is certainly easier to find and you don’t have to pay five bucks to enter the area, as with Sea Pines.
This three-acre Heritage Preserve dates back to at least the 1300s. The heart of Green’s Shell Enclosure comprises a low embankment, part of the original fortified village. Don’t expect to be wowed—shell rings are a subtle pleasure.
As is the case with most shell rings, the shells themselves are underneath a layer of dirt. Please don’t disturb them.
To get to Green’s Shell Enclosure, take a left at the intersection of U.S. 278 and Squire Pope Road. Turn left into Greens Park, pass the office on the left, and park. The entrance to the shell enclosure is on the left behind a fence.
You’ll see a small community cemetery that has nothing to with the shell ring; veer to your right to get to the short trail entrance. There is no camping allowed.
