A firebox or firepit is the part of the fireplace where fuel is combusted, in distinction from the hearth, chimney, mantel, overdoor and flue elements of the total fireplace system. [1] The firebox normally sits on a masonry base at the floor level of the room. [2] Some fireboxes are large in proportion so that a person could actually walk inside, or in extreme cases, have a small meeting using built-in benches inside. An example of the latter oversized construction can be found in the great hall of Muchalls Castle in Scotland.
