The H.L. Hunley, the world’s first successful combat submarine, can now be seen completely unobstructed, at the Charleston conservatory in Charleston, SC.

Preservation is not yet completed. Conservators need to remove corrosion from the iron hull and then add chemicals so that the submarine can be shown in open air, but still, you can now view the whole thing.

While the Hunley was a major accomplishment for the Confederacy, it was also a source of tragedy, with three full crews dying inside her hull. Pictures of the final crew are on display next to the tank that holds the sub.
