Glenville Historic District, also known as Sherwood's Bridge, is a 33.9 acres (13.7 ha) historic district in the Glenville neighborhood of the town of Greenwich, Connecticut. It is the "most comprehensive example of a New England mill village within the Town of Greenwich". It "is also historically significant as one of the town's major staging areas of immigrants, predominantly Irish in the 19th century and Polish in the 20th century" and remains "the primary settlement of Poles in the town". Further, "[t]he district is architecturally significant because it contains two elaborate examples of mill construction, designed in the Romanesque Revival and a transitional Stick-style/Queen Anne; an excellent example of a Georgian Revival school; and notable examples of domestic and commercial architecture, including a Queen Anne mansion and an Italianate store building.": 13 It was listed on the National Register of Historic Places in 2007. At that time, it included 43 contributing buildings, 4 other contributing structures, and 4 contributing sites.
The district is drawn to include the core area of the neighborhood, and it includes a mill property, although it omits an adjacent condominium complex. It is drawn also to exclude "a shopping center and the one-family houses of Angelus Drive, both areas dating from the 1960s." It also excludes various other commercial and residential areas of Glenville.: 22 Significant properties in the district include:
