The Laurel Hill Historic District is a predominantly residential historic district south of downtown Norwich, Connecticut. The district was added to the National Register of Historic Places on October 26, 1987. It extends south from the Shetucket River along Laurel Hill Avenue, River Avenue, and Spruce Street. This area was developed as a residential district beginning in 1850, and includes a significant number of well-preserved Italianate and Gothic Revival houses.

The Yantic River forms at the confluence of the Deep River, Sherman Brook, and Exeter Brook about 4 miles (6.4 km) east of Colchester, Connecticut. It runs for 14.2 miles (22.9 km) and flows into the Shetucket River in Norwich, forming the Thames River. The Yantic River is a popular whitewater paddling destination with a mix of quickwater and Class I-III whitewater. It passes through the towns of Lebanon, Bozrah, and Norwich. The USS Yantic was named after the river.

The Shetucket River is a tributary of the Thames River, 20.4 miles (32.8 km) long, in eastern Connecticut in the United States. It is formed at Willimantic by the junction of the Willimantic and Natchaug rivers. It flows southeast and south. Approximately 4 miles (6 km) northeast of Norwich it receives the Quinebaug River and broadens into a wide estuary which stretches southeast for approximately 5 miles (8 km) and joins the Thames estuary on the south side of Norwich. The river flows through a rural section of New England, despite the historical presence of industry in the surrounding region. Parts of the rivers have been designated by the federal government as the Quinebaug and Shetucket Rivers Valley National Heritage Corridor. The National Park Service describes the river valley as the "last green valley" in the Boston-to-Washington megalopolis. In nighttime satellite photos, the valley appears distinctively dark amidst the lights of the surrounding urban and suburban regions.

The Downtown Norwich Historic District is a historic district representing the core of the downtown area of the city of Norwich, Connecticut in the United States. It was listed on the National Register of Historic Places in 1985. It includes 115 contributing buildings and one other contributing structure over a 64-acre (26 ha) area. Several buildings in the historic district are also individually listed on the National Register, including the Norwich Town Hall, the Telephone Exchange Building and the Carroll Building.Norwich was settled by English colonists in the 17th century, and its first wharf was built in 1684. It developed rapidly as a shipping port, with economic activity focused near the waterfront at the confluence of the Shetucket, Yantic, and Thames Rivers. The downtown developed as a linear area just north of the main port area, Main Street forming an east–west axis. The oldest surviving commercial building dates to 1742, and the oldest house to 1745. A major fire in the downtown in 1793 encouraged a shift to brick construction, but growth was squelched by the economic blockades associated with the War of 1812. The downtown's architecture is consequently dominated by Greek Revival andlate 19th and early 20th century architecture, which was built when the city was an important point for the transshipment of goods by either rail or ship. By this time, the city's economy had diversified to include banking, textiles, and other water-powered industry. The downtown area includes many intact 18th and 19th-century buildings centered on the now-picturesque harbor.

The Carroll Building in Norwich, Connecticut, also known as the Flat Iron Building, was built in 1887. It was listed on the National Register of Historic Places (NRHP) in 1982. It is included in the Downtown Norwich Historic District, which is also listed on the NRHP. Originally used as offices and retail stores, the building is now currently used primarily as an apartment building. The Carroll Building is located on a triangular tract created by the intersection of Main and Water Streets. The building is highly visible from Washington Square (west side of downtown) and is one of the most noticeable aspects of the downtown streetscape. The building is currently vacant.

Norwich City Hall is the seat of municipal government in Norwich, Connecticut. It is located at Union Street and Broadway, prominently overlooking the city's central business district. Built in 1870-73, when Norwich was still a town, it has served as the seat of municipal government since then.

The John F. Slater House, also known as the Elks Club, is a historic building in Norwich, Connecticut. It was built in brick for John Fox Slater around either 1827 or 1843. It was added to the National Register of Historic Places in 1985 as part of the Downtown Norwich Historic District as "the most elaborate Greek Revival building in the downtown", and it is fronted by a monumental Corinthian portico. The design of the house has been attributed to John Bishop, a builder from New London who was responsible for the Huntington Street Baptist Church. The house was later owned by the local lodge of Elks, who used the building as their clubhouse. In 1914-15 they built a large but complementary rear addition, designed by architects Cudworth & Woodworth and contractors Doyle & Murphy, the same team that would build the Willimantic Elks Club ten years later. The building was vacant as of January 2014.

The Telephone Exchange Building is a historic building at 23 Union Street in downtown Norwich, Connecticut, behind Norwich Town Hall. Built in 1906-07, it was the first purpose-built telephone exchange building in the city, and is a little-altered example of period exchanges built by the Southern New England Telephone Company. The building now houses city offices. It was listed on the National Register of Historic Places on November 28, 1983.

The Little Plain Historic District is a predominantly residential historic district located in Norwich, Connecticut. When originally listed in 1970, it was centered on Little Plain Park, located about halfway between modern downtown Norwich and the Norwichtown green, the colonial center of the town. From the late 18th century onward this area became a desirable and fashionable area to live, as it was closer to the growing port area of the city. The area was mostly built out by about 1875, and features a rich concentration of Greek Revival, Gothic Revival and Italianate houses, although older and later styles are also represented. The district was listed on the National Register of Historic Places in 1970 and enlarged in 1987. The 1987 enlargement expanded the district southward along Union Street and Broadway, to abut the Downtown Norwich Historic District, and increased the district's size from 30 acres (12 ha) to 38.8 acres (15.7 ha).Little Plain Park is a long and narrow triangular parcel bounded on the east by Broadway, the wet by Union Street, and the south by Crossway Street. It was donated to the city by Deacon Jabez Huntingdon and Hezekiah Perkins, whose houses stand at 181 and 185 Broadway. Both are prominent examples of Georgian architecture to which Federal styling was later applied. The Dewitt-Sigourney House, at 189 Broadway, was built later in the 19th century for a ship's captain, and is a more pure example of Federal styling. The Woodhull and Johnson Houses at 167 and 171 Broadway are fine examples of Greek Revival architecture, built for merchants and ship owners.The district includes buildings designed by Norwich architects James A. Hiscox and Joshua W. Shepard.
