USS Constitution restricted ship spaces and restoration zones

USS Constitution ('Old Ironsides'), berthed at the Charlestown Navy Yard, is the world's oldest commissioned warship afloat and is operated with public tours of many decks through the USS Constitution Museum and crew-led programs. Several interior spaces-crew-only areas, maintenance zones, and lower holds-are restricted and accessed only by crew, researchers, or during special guided programs. Major restoration and drydock work on the ship occurs in controlled areas of the Navy Yard that are not continuously open to casual visitors.
