Octagonal buildings and structures are characterized by an octagonal plan form, whether a perfect geometric octagon or a regular eight-sided polygon with approximately equal sides.
Octagon-shaped buildings date from at least 300 B.C. when the Tower of the Winds in Athens, Greece, was constructed. Octagonal houses were popularized in the United States in the mid-19th century by Orson Squire Fowler and many other octagonal buildings and structures soon followed.
