Of elongated shape (5 x 2.5 meters or 16 x 8 ft), room B gave us a beautiful, white and black mosaic whose designs form Greek crosses. It is kept in the archaeological museum.The wall decor, though very incomplete, has been restored. The paintings of low and mid areas mimic the marble. The upper part to the big green circles with red or blue disks and florets evoke the wallpaper. Room C, with similar dimensions, was decorated with red signs on which apples stand out whose relief and light effect the painter was able to beautifully restore. The paving of this room has not been found. The modest rooms B and C next to room A were probably resting rooms.
