Lightwell

In architecture, a lightwell, light well or air shaft is an unroofed external space provided within the volume of a large building to allow light and air to reach what would otherwise be a dark or unventilated area. Lightwells may be lined with glazed bricks to increase the reflection of sunlight within the space.

Lightwells serve to reduce the necessity for electric lighting, add a central space within the building, and provide an internal open space for windows to give an illusion of having a view outside.

A subterranean lightwell at the front of a building to provide light to a basement is called an area (or areaway in North American usage).

Ancient history

The lightwell was used in ancient civilizations, such as the Egyptians[1] and at the Palace of Knossos on Minoan Crete.[2] There are also instances of lightwell use by the Romans.[3]
