7 Best Sights in New Haven, Mystic, and the Coast, Connecticut

The world's first nuclear-powered submarine, USS Nautilus (SSN-571)—and the first submarine to complete a submerged transit of the North Pole (in 1958)—was launched and commissioned in Groton in 1954. The Nautilus spent 25 active years as a showpiece of U.S. technological know-how and is now permanently docked at the Submarine Force Museum, a couple of miles upriver from where the sub was built. Visitors are welcome to climb aboard and explore. The museum, just outside the entrance to Naval Submarine Base New London, is a repository of thousands of artifacts, documents, and photographs detailing the history of the U.S. Submarine Force component of the U.S. Navy, along with educational and interactive exhibits.

New Haven's manufacturing history dates to the 19th century, but the city owes its fame to merchant Elihu Yale. In 1718, his contributions enabled the Collegiate School, founded in 1701 at Saybrook, to settle in New Haven and change its name to Yale College. In 1887, all of its schools were consolidated into Yale University. This is one of the nation's great institutions of higher learning, and its campus holds some handsome neo-Gothic buildings and noteworthy museums. Student guides conduct hour-long walking tours that include Connecticut Hall in the Old Campus, one of the oldest buildings in the state, which housed a number of illustrious students—including Nathan Hale, Noah Webster, and Eli Whitney. Tours start from the visitor center.

Since its founding in 1832, this art gallery has amassed more than 200,000 works from around the world, dating from ancient Egypt to the present day. Highlights include works by Vincent van Gogh, Edouard Manet, Claude Monet, Pablo Picasso, Winslow Homer, and Thomas Eakins, as well as Etruscan and Greek vases, Chinese ceramics and bronzes, early Italian paintings, and a collection of American decorative arts that is considered one of the world's finest. The gallery's landmark main building is also of note: Opened in 1953, it was renowned architect Louis I. Kahn's first major commission and the first modernist building on the neo-Gothic Yale campus.

The library's collection of literary papers, early manuscripts, and rare books include a Gutenberg Bible and original Audubon bird prints; the exhibition spaces on the ground floor and mezzanine are open to the public. The building that houses them is an attraction in its own right: the walls are made of marble cut so thin that the light shines through, making the interior a breathtaking sight on sunny days. Introductory tours for individuals are offered on Saturday afternoons; group tours are Yale-led and require advance registration at the Yale Visitor Information Center

It was here (legend has it), on the Groton side of the Thames River, that the infamous traitor Benedict Arnold stood watching the important port of New London (a supply center for the Continental Army and friendly port for Connecticut privateers) burn in 1781 during the Revolutionary War. Whether Arnold actually stood there is open to question; but the American defenders of Ft. Griswold were massacred by Arnold's British troops during the Battle of Groton Heights—and New London did burn according to his orders. The 134-foot-high Groton Monument, which you can climb for a sweeping view of the river and New London, is a memorial to the fallen. The adjacent Monument House Museum has historic displays; the Ebenezer Avery House, on the grounds and recently restored, is where the wounded were sheltered in 1781.

Bordered on its west side by the Yale campus, the New Haven Green is a fine example of early urban planning. Village elders set aside the 16-acre plot as a town common as early as 1638. Three early-19th-century churches—the Gothic Revival-style Trinity Episcopal Church, the Federal-style Center Congregational Church, and United Church—have contributed to its present appeal. For a year, from September 1839 to August 1840, survivors of the slave ship Amistad were incarcerated in a jail on the east side of the green and were brought out of jail to exercise there. An Amistad memorial now resides at the site of the former jail. Besides being a pleasant urban park, the Green is also the venue for festivals and events throughout the year.

The 100-acre cluster of redbrick buildings you see overlooking the Thames River makes up one of the four U.S. military academies. Visitors are welcome, and security is obviously tight, but being there when the Coast Guard training ship, the barque Eagle, is in port is a special treat. A small museum, located in Waesche Hall on the grounds, explores the Coast Guard's 230+ years of maritime service and includes some 200 ship models, as well as figureheads, paintings, uniforms, life-saving equipment, and cannon.
