About
About Old Stone Fort
Middle Woodland hilltop enclosure (80–550 CE) of dry-stacked limestone and earth walls 2.75 km perimeter, 52 ha, enclosing promontory between Duck and Little Duck rivers with 1.5–4.5 m wide walls up to 6 m tall sections. Ceremonial rather than defensive: narrow entrances oriented to summer solstice sunrise and equinox, yielding Hopewell-associated rock art and burned structures. Interpreted as calendrical theater.
Why it mattersLargest hilltop enclosure in SE US; key for Woodland calendric astronomy and promontory enclosure tradition.
