Ernst Flentje House

The Ernst Flentje House, located at 129 Magazine Street in Cambridge, Massachusetts, is a historic three-story wood frame apartment building that showcases the adaptive reuse of architectural styles. Originally built in 1866 as a single-family residence with a distinctive mansard roof, it was transformed in 1900 by Ernst Flentje into a vibrant three-unit apartment house. Noted for its exuberant decorations, this unique structure was added to the National Register of Historic Places in 1983, making it a significant landmark for both tourists and researchers interested in architectural history.
