Definition of atrium

The word "atrium" has its roots in ancient Roman architecture and design. In Latin, "atrium" means "hall" or "courtyard." In Roman homes, the atrium was a central outdoor space that served as a gathering area, often surrounded by a portico or wrap-around balcony. It was typically surrounded by windows and had a skylight or oculus (a circular opening) in the ceiling to allow natural light to pour in. The atrium was an important feature of Roman villas and townhouses, as it brought light and air into the home. Over time, the concept of an atrium evolved to be used in other types of buildings, such as libraries, museums, and hospitals. Today, the word "atrium" is used to describe a large, open space with a high ceiling, often used as an entrance or gathering area.
