The village of Barrington has the largest residential historic district in Illinois and is noted for its Victorian, Victorian Gothic, Queen Anne, and other popular late-19th century forms of architecture. Among Barrington's notable buildings is the Octagon House, also known as the Hawley House. Claimed to be built around 1860, although the oldest home in Barrington Village is on North Avenue dating to 1872, the Octagon House is listed on the National Register of Historic Places; although initially a residence, it now serves as a commercial property.
