"The strong hold of Conway is further remarkable for exhibiting another domestic refinement, not found, except at , in any contemporary building. A hearth is recessed into the wall, and has a rising from it for the passage of the smoke into the air. It is true, that after this period, flued fireplaces were sometimes made in rooms that had been erected without them, but the chimney in Conway Castle, and a similar one at Kenilworth [Castle], appear as if they had formed part of the original edifices."
