Glass-roofed halls, also known as atria, are large, open-air spaces that are covered by a glass roof. They are often used in public buildings such as shopping malls, airports, and museums, and can be found in many different architectural styles. Atria provide natural light and ventilation, and can be used to create a pleasant atmosphere in an otherwise enclosed space. They are also often used to create a visual connection between the interior and exterior of a building.
