What is an atrium in the context of architecture?

In the context of architecture, an atrium refers to a high ceiling room, particularly one that is often open to the sky or features large windows to allow natural light into the space. This architectural feature has its roots in ancient Roman houses, where it served as a central area that connected various rooms and provided a welcoming space.

Atriums typically are characterized by their spaciousness and can function as both light wells and communal areas, often enhancing the aesthetic and functional qualities of buildings. This design element is prominent in modern architecture, where it is used to create inviting and airy environments within larger structures such as hotels, office buildings, and public spaces.

The other options do not accurately describe an atrium in architectural terms. While an open rectangular court is a feature of certain churches, it is not synonymous with an atrium. Similarly, the concept of an enclosed garden space or an ancient Greek theater does not align with the traditional definition of an atrium.
