The Newton Downtown Historic District (outlined in blue on the map below) consists of 85 properties (some of which contain more than one storefront). It was officially listed on the National Register of Historic Places in September 2014. The National Register is the federal list of districts, sites, buildings, & structures significant in American history, architecture, archaeology, engineering, and culture. National Register districts are shown to be important in the history and/or development of their community. Properties contributing to the significance of an historic district are at least 50 years old and retain a high degree of historic integrity.

The buildings marked on the map are individually eligible for the National Register due to architectural or historic significance. (Please note that the historic building names are being used in the descriptions below.)
