Have you ever seen an eight-sided house? Here's what makes them so unique.

Houses come in all shapes and sizes — boxes, domes and, sometimes, octagons. If you've never heard of an octagon house, these cool, quirky structures were an American fad back in the mid-1800s, when phrenologist Orson Squire Fowler touted the architectural efficiency of eight-sided abodes. He believed so much in octagon-shaped homes that he even wrote a book called The Octagon House: A Home for All. One look at the floor plan of an historic octagon house and you can kind of see what all the hubbub was about: An octagon-shaped footprint can yield four big square rooms and four additional triangle rooms. Also, we love how all the rooms connect to each other around a central staircase. 

There are still a number of octagon homes in existence from that era, many of which have been entered into the National Register of Historic Places. There are also modern octagon homes that embrace the polygonal architecture for reasons both aesthetic and pragmatic.

Here are seven octagon homes from cities all over the country, many of which are currently on the market.
