Freebase

  1. Atrium

    In architecture, an atrium is a large open space located within a building. Atria were a common featured in Ancient Roman dwellings, providing light and ventilation to the interior. Modern atria, as developed in the late 19th and 20th centuries, are often several stories high and having a glazed roof and/or large windows, and often located immediately beyond the main entrance doors. Atria are a popular design feature because they give their buildings a "feeling of space and light". Fire control is an important aspect of contemporary atrium design due to criticism that poorly designed atria could allow fire to spread to a building's upper stories more quickly.
