Built in 1876, it originally served as an interchange point between ocean-going freighters and the rail network of the Central Vermont Railroad.

The Groton Bank Historic District, commonly known as Groton Heights, is a primarily residential 50-acre (20 ha) historic district in the City of Groton (within the Town of Groton) in Connecticut. The district was added to the National Register of Historic Places on March 24, 1983.The district has an inverted U-shape formed by Thames, Broad, and Monument Streets, and its boundaries are based on an 1868 map to include an area developed mostly during 1820–1860, reflecting a period of growth when Groton was a significant whaling and shipbuilding center. Groton was settled by English colonists in the mid-17th century, but it has few remaining colonial-era structures, since many were destroyed during the Battle of Groton Heights in the American Revolutionary War. A number of post-independence 18th-century houses survive, including the Major Noyes Barber house, built in 1810, which is a Federal style structure.The district contains a cross-section of architectural styles from its periods of growth. The Groton Heights Baptist Church was built in 1878 and is an example of Italianate architecture, and the Thomas Miner House on Monument Street, built about 1894, is an example of Queen Anne architecture. Non-residential buildings in the district include a number of late 19th-century commercial blocks on Thames Street, as well as the Bill Memorial Library, a high-style example of Richardsonian Romanesque design by Stephen C. Earle.

Fort Griswold is a former American defensive fortification in Groton, Connecticut named after Deputy Governor Matthew Griswold. The fort played a key role in the early stages of the American Revolutionary War, in correspondence with Fort Trumbull on the opposite side of the Thames River. Griswold defended the port of New London, Connecticut, a supply center for the Continental Army and friendly port for Connecticut-based privateers who targeted British shipping. The 17-acre site is maintained as Fort Griswold Battlefield State Park by the Connecticut Department of Energy and Environmental Protection.

The National Coast Guard Museum is a museum planned for construction in New London, Connecticut, an historic seaport at the mouth of the Thames River on Long Island Sound that is the home of the United States Coast Guard Academy. The Coast Guard Museum Association, which has been working to create the museum since 2001, had hoped to break ground on the building in 2018. However, in 2019 David Collins, staff writer for the New London Day, wrote that the museum, "keeps slipping deadlines, year by year, and it's beginning to look like it could sink hopelessly underwater before any rescue is mobilized."Construction of the museum officially started August 19, 2022 with a "keel laying ceremony".The Coast Guard and the Space Force are the only two out of America's six service branches that do not yet have a dedicated museum; the Army, Marines, Navy and Air Force already have museums.The museum has been given a site on the Thames River by the City of New London.The federal government has committed $30 million, and the State of Connecticut has committed $20 million to construct a pedestrian bridge necessary to provide pedestrian access to the museum over the main railroad track connecting New York and Boston. The Museum Association expects to raise the bulk of the necessary funds from private donations. In 2019 Lockheed Martin, which owns the locally manufactured Sikorsky Helicopters, pledged $1 million.The proposed five or six-story, 80,000 square feet building will include an outdoor concert pavilion where the United States Coast Guard Band and other groups can give concerts.

New London Union Station is a railroad station on the Northeast Corridor located in downtown New London, Connecticut, United States. Union Station is a station stop for most Amtrak Northeast Regional trains and all CTrail Shore Line East commuter rail trains, making it the primary railroad station in southeastern Connecticut. It serves as the centerpiece of the Regional Intermodal Transit Center, with connections to local and intercity buses as well as ferries to Long Island and Fishers Island, New York, and Block Island, Rhode Island. The station has one side platform and one island platform serving the two-track Northeast Corridor; the latter platform also serves a siding track that connects to the New England Central Railroad mainline. Rail service to New London began with the New London, Willimantic, and Palmer Railroad in 1848 and the New Haven and New London Railroad in 1852. The original stations were each replaced in the 1860s; after several consolidations, they were served by the Central Vermont Railway (CV) and New York, New Haven and Hartford Railroad (New Haven) by the 1870s. After one of the stations burned in 1885, a new three-story brick union station was erected in 1887. It was the last and largest railroad station designed by famed architect H. H. Richardson, and his best according to biographer Henry-Russell Hitchcock.Passenger service declined in the 20th century; all CV passenger service to New London ended in 1949. The New London Redevelopment Agency began planning in 1961 to demolish the station as part of urban renewal. Amtrak took over passenger service in May 1971; Union Station was added to the National Register of Historic Places the next month following a local effort. After several years of controversy over whether to demolish or preserve the structure, it was purchased by architect George M. Notter in 1975. Notter's firm renovated the station for combined use by Amtrak and commercial tenants; it was the first station to be restored for Amtrak's use, and one of the earliest cases of adaptive reuse of an industrial-age building in New England. Shore Line East commuter service joined Amtrak intercity service at the station in 1996. High-level platforms were added in 2001 to serve the new Acela Express service. A second renovation in 2002–03 restored the exterior and returned the waiting room to its original configuration. The planned National Coast Guard Museum, which will be located across the tracks from the station, will include a long-planned footbridge over the tracks.

The Ebenezer Avery House was originally located on Latham Street and Thames Street in Groton, Connecticut. The construction date is unknown, but it is believed to be from the 1760s and was the house of Ebenezer Avery. It was the home where the British brought their injured soldiers after the Battle of Groton Heights on September 6, 1781. In 1971, the house was moved to Fort Griswold Battlefield State Park in Groton and restored. The historic house museum is maintained by the Avery Memorial Association.

The Groton Monument, sometimes called the Fort Griswold Monument, is a 135 feet (41 m) granite obelisk in Groton, Connecticut dedicated to the defenders who fell during the Battle of Groton Heights on September 6, 1781. The monument bears a plaque describing the events of the Battle of Groton Heights, and another plaque with the names of the Americans who died in the battle. Lightning destroyed the capstone in 1918 and damaged the adjacent Monument House Museum which features exhibits about the Revolutionary War. Visitors can climb the monument and visit the museum from Memorial Day through Labor Day. The Groton Monument is located in Fort Griswold Battlefield State Park, which includes Fort Griswold.

The Winthrop Mill (also known as the Old Town Mill or "Comstock Mill") is a historic mill building on Mill Street in New London, Connecticut.

The U.S. Post Office-New London Main is located at 27 Masonic Street in New London, Connecticut.

The Hodges Square Historic District of New London, Connecticut encompasses a working-class residential area north of the city's central business district. It is located between the campus of the United States Coast Guard Academy and Interstate 95, and is bounded on the west by Williams Street and the east by the Thames River. This area developed as a modest working-class residential area in the mid-19th century, when New London's economy began shifting from one based on maritime pursuits to one based on manufacturing. The area's residents were typically employed in nearby silk manufacturing operations, or by the Central Vermont Railroad, which had a roundhouse and service yard nearby. Hodges Square, a small cluster of commercial buildings, forms the economic center of the neighborhood.The district was listed on the National Register of Historic Places in 2017.
