This dungeon in Charleston is a pre-revolutionary dungeon and everything is completely original. We took a tour of it and you can see part of the only remaining sea wall that used to stretch in front of Charlston. It was very dark and musty down in the dungeon and it must have been so awful for prisoners! The upstairs of the building has a big, beautiful hall which is still used for receptions and is quite the opposite of the dungeon! It is also supposedly haunted. This is a fun activity to do for a few hours with your family.
