What Is a Cupola Roof?

Cupolas serve both decorative and practical purposes.

Cupolas are a popular way to add character to roof tops. They have a long history and have been integrated into modern architecture as a way to bring light and air into a building.

Description

Cupolas are installed on top of roofs and look like domes or boxes mounted on a square or round base. Many look like small buildings and have weather vanes mounted on top. Some cupolas have a practical purpose, while others are only decorative.

History

Large round cupolas originated in the architecture of the Middle East. Over time the design spread to Russia, Spain, Vienna, and Austria. Cupolas can be seen topping many churches in these countries. By the 19th century cupolas were common accents on houses in the United States.

Function

Ventilation is the primary function of a cupola. Most cupolas have adjustable vents to control airflow into attic spaces. Cupolas are also used to bring more light into a room and increase the sense of internal space. Some cupolas are built large enough to walk into and offer a high vantage point.
