Building at 29–31 River Street - Credit: Wikimedia Commons
The Building at 29–31 River Street in Southbridge, Massachusetts, is one of two once similar triple-deckers built during a housing boom related to the success of the nearby Hamilton Woolen Company. Of six such houses built in the 1910s and 1920s on River Street, only it and 25-27 River Street remain. The building was listed on the National Register of Historic Places in 1989, since when its historic integrity has been compromised. Read more on Wikipedia
