Detail of Roman Hypocaust
This is all that remains of the Hypocaust, a way of heating public baths and private houses. The floor was raised off the ground by pillars, called pilae stacks, and spaces were left inside the walls so that the hot air and smoke from the furnace (praefurnium) would pass through these enclosed areas and out of flues in the roof, thereby heating but not polluting the interior of the room or bath.
