Greeneville is a neighborhood of the city of Norwich, Connecticut, located northeast of downtown Norwich along the west bank of the Shetucket River. Most of the neighborhood is designated Greeneville Historic District, a historic district that is listed on the National Register of Historic Places. The district was listed on the National Register in 2005 and includes 683 contributing buildings, seven other contributing structures, and one other contributing site over a 300 acres (120 ha) area.The district is drawn to "correspond to the village as it was laid out in 1833, but also include additional streets laid out and developed in the late nineteenth and early twentieth centuries to accommodate population growth. Areas north and south of the district boundaries were excluded...." as those areas included undeveloped land, or fewer contributing relative to non-contributing buildings, or reflected a "shift in architectural character.": 52 According to the Connecticut Trust for Historic Preservation the district "is a historically significant industrial village that was created to support and sustain water-powered industry from 1828 to about 1940. Much of the enduring success of this industrial enterprise can be attributed to the entrepreneurial vision of industrialist William P. Greene (1795–1862). His development of this planned community and a company to deliver a centralized power system, combined with significant technological infrastructure improvements in the late 19th century, supported the largest industrial presence in Norwich. Although nominally a part of the City of Norwich after 1875, from its creation in 1833 until after World War I Greeneville remained a relatively independent and self-sufficient, working-class community-an evolution fully expressed by the district's large, cohesive collection of generally well-preserved domestic, institutional and commercial architecture. While much of the architecture has the vernacular character expected in a mill town, the district also includes representative examples of the major styles of the period, including Greek Revival, Second Empire, Italianate, and Carpenter Gothic."

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 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.

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.
