The largest coastal fortification in the United States is at Fort Adams State Park, home to the Newport Folk and Jazz festivals. From mid-May through Columbus Day, the nonprofit Fort Adams Trust offers tours of the fort where soldiers lived from 1824 to 1950. You can explore the fort's overlooks and tunnels or walk along its impressive walls. The ciews of Newport Harbor and Narragansett Bay are exquisite. The fort is reputed to be haunted and is often open for ghost hunting
tours in the days leading up to Halloween.
