The fort was named after the second president of the United States, John Adams.
The structure was designed according to the Third System of US coastal fortification.
It served as the summer residence of the Secretary of the Navy during the early 20th century.
The fort's underground tunnels, known as counterscarp galleries, were engineered to defend the dry moat.
Construction required nearly 30 years and used millions of bricks sourced from the local region.
The park is the site of the original Newport Jazz Festival, which began here in the 1950s.
It was used as a base during the War of 1812, although the current stone structure was built later.
The masonry includes granite bastions designed to withstand 19th-century naval bombardment.
Fort Adams State Park occupies the northern tip of Newport Neck, providing panoramic views of Narragansett Bay and the East Passage. The site features the historic Fort Adams, a massive coastal fortification constructed between 1824 and 1857. It remains the largest coastal fortification in the United States and serves as a primary venue for major regional music festivals. Visitors can explore the fort's interior via guided tours or traverse the public grounds and surrounding waterfront trails. The park also hosts the Sail Newport facility, which facilitates national and international sailing regattas. Expansive lawns offer direct water access for kayaking and windsurfing. The grounds are part of the broader Newport Harbor entrance defense system. Recreational facilities include soccer fields and picnic areas dispersed throughout the 92-acre property.

Do not attempt to enter unmarked or gated areas within the fortification for safety reasons.
Guided fort tours are seasonal, typically running from late spring through autumn; grounds remain accessible year-round.
