USS Constitution ('Old Ironsides') at Charlestown Navy Yard

USS Constitution, nicknamed 'Old Ironsides,' is the world's oldest commissioned naval vessel still afloat; it was launched in 1797 and is permanently berthed at the Charlestown Navy Yard. Photographs of the tall ship against the Boston skyline, especially during parades and the July 4th celebrations, are frequently shared on social media and in travel coverage. The ship and its public tours draw both local and international visitors who commonly post images and videos online.
