Octagon Schoolhouse
Also known as "eight-square" and "ink-bottle" schools.

Octagon School

The Penn's Park Schoolhouse in Wrightstown, PA is the only remaining intact octagonal schoolhouse of the at least 15 that were once in Bucks County, PA.  The eight sided style of school house was popular in the English Quaker settled areas of the Delaware Valley (Southeast PA, New Jersey and Delaware) at the turn of the 19th century.  
These existed well before octagonal houses were popular in the mid 19th century.  The style spread quite far, as indicated by surviving examples I've found in upstate New York, Ohio, Illinois and Wisconsin.  

The form allowed natural light in at any time of day, a breeze could blow through from any direction on hot days and central wood/coal stoves heated the building evenly.  It was more difficult though, to send naughty kids to "the corner" for punishment.
