Witch Windows, Vermont

In American vernacular architecture, a witch window—also known as a Vermont window, a coffin window, or a sideways window—is a diagonal, rotated window. But why is this simple architectural twist called a "witch window"?

The name appears to come from a superstition that witches cannot fly their broomsticks through the tilt. These types of windows are found almost exclusively in or near Vermont, generally in the central and northern parts of the state, and principally in farmhouses from the 19th c.
