HL Hunley submarine, in a faceless warehouse at a working dockyard north of downtown, rests in a 90,000-gallon tank of water like some strange top-secret science experiment. In 1864 the Confederate Hunley completed the world's first submarine mission by sinking the Union's USS Housatonic , only to vanish immediately afterwards. In 1995 it was discovered off Sullivan's Island and carefully brought to shore. On weekends you can visit the Hunley and see creepy facial reconstructions of her eight crew members.
