An atrium is a large open space within a building, often featuring a high ceiling and natural light. It serves as a central gathering area, connecting different parts of the structure. Atriums are commonly found in places like hotels, shopping malls, and office buildings, enhancing the aesthetic appeal and providing a welcoming atmosphere. In ancient Roman architecture, the term atrium referred to the central courtyard of a house, which was typically open to the sky. This design allowed for ventilation and light, making it a vital part of the home. Modern atriums continue to serve similar purposes, promoting social interaction and a sense of openness.
