A cupola is a small, dome-like structure that sits on top of a building. It is often used for decoration or to provide light and ventilation to the interior space. Cupolas can be found in various architectural styles and are typically made of materials such as metal, wood, or glass.
One famous example of a cupola is the dome of the Pantheon in Rome. The Pantheon's cupola is a corbeled dome, which means it is formed by building up layers of material that gradually overhang each other until they meet in the middle. This architectural technique creates a visually striking and structurally sound cupola.
In addition to its aesthetic appeal, a cupola can also serve practical purposes. For example, it can provide a natural source of light through windows or an open top, as well as improve ventilation within a building. Cupolas are commonly found on churches, government buildings, and historic structures.
