Chimney breast

A chimney breast is a portion of a chimney which projects forward from a wall to accommodate a fireplace. Typically on the ground floor of a structure, the masonry extends upwards, containing a flue which carries smoke out of the building through a chimney stack. Chimney jambs similarly project from the wall, but they do so on either side of the fireplace and serve to support the chimney breast. The interior of a chimney breast is commonly filled with brickwork or concrete.
