fireplace

n. section of a chimney which opens into a room in which a fire can be lit; outdoor structure in which a fire can be lit

A fireplace is an architectural element consisting of a space designed to contain a fire, generally for heating but sometimes also for cooking. The space where the fire is contained is called a firebox or firepit; a chimney or other flue allows gas and particulate exhaust to escape the building. While most fireplaces are constructed in building interiors, sometimes outdoor fireplaces are created for evening warmth, outdoor cooking or decorative purposes.
