Hot Room Floor and Walls

View looking south at the well-preserved and partially reconstructed Hot Room (caldarium).  Note the small columns that supported the floor—a portion of the floor (lower left) is a modern reconstruction. 

Left of center the "lump" of material is part of the original flooring and behind it to the left some of the original pipes are barely visible.  The modern reconstruction of this "system" is visible on the lower left side of the image.
