The Belleville Historic District is a historic district in Belleville, Illinois. The primarily residential district consists of an irregularly shaped area on the east side of Belleville. 70 buildings are included in the district, all of which are contributing buildings to its historic character. The homes in the district represent Belleville's residential development from 1830 to 1900. Many of the houses were designed in a vernacular cottage style popular among the city's German immigrants; while common in Belleville and other Metro-East cities, the style is little seen elsewhere in the state. Formal architectural styles such as Greek Revival and Italianate are also prevalent in the district.The district was added to the National Register of Historic Places on November 7, 1976.
