The Queen Anne's Revenge Project brought the massive gun ashore Wednesday. Onlookers cheered as the eight-foot-long gun was raised above the water's surface.
The project is named after the flagship and has been working since 1997 to salvage artifacts from the wreck.
The gun was on public display Wednesday in front of the state Maritime Museum in Beaufort before being taken to a laboratory for further study.
The cannon is encased in a cement-like shell of sand, salt and barnacles. It could take years for researchers to learn exactly what the shell contains in addition to the gun.
