The Battle of Groton Heights (also known as the Battle of Fort Griswold, and occasionally called the Fort Griswold massacre) was a battle of the American Revolutionary War fought on September 6, 1781 between a small Connecticut militia force led by Lieutenant Colonel William Ledyard and the more numerous British forces led by Brigadier General Benedict Arnold and Lieutenant Colonel Edmund Eyre. Lieutenant General Sir Henry Clinton ordered Arnold to raid the port of New London, Connecticut, in an unsuccessful attempt to divert General George Washington from marching against Lord Cornwallis's army in Virginia. The raid was a success, but the Connecticut militia stubbornly resisted British attempts to capture Fort Griswold across the Thames River in Groton, Connecticut. New London was burned along with several ships, but many more ships escaped upriver. Several leaders of the attacking British force were killed or seriously wounded, but the British eventually breached the fort. As the British entered the fort the Americans surrendered, but the British continued firing and killed many of the defenders. However, the high number of British casualties in the overall expedition against Groton and New London led to criticism of Arnold by some of his superiors. The battle was the last major military encounter of the war in the northern United States, preceding and being overshadowed by the decisive Franco-American siege of Yorktown about six weeks later.

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.

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 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.

The Gold Star Memorial Bridge is a pair of steel truss bridges that carry both Interstate 95 and U.S. Route 1 across the Thames River between New London, Connecticut, US and Groton, Connecticut. The bridge is the largest structure in the state with more than 1,000,000 sq ft (93,000 m2) of deck area, and the longest bridge in the state at 6,000 feet (1,829 m). Its 11 highway lanes accommodate an average daily traffic of 117,000 vehicles. The bridge is actually a set of twin bridges, but they are generally spoken of using the singular "bridge;" the local media and residents refer to it as "The Goldstar".

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.
