The House of the Dragon, so denominated because of the sea dragon depicted in one of its floor mosaics visible at the Archaeological Museum of Monasterace, is one of the most luxurious residences of Kaulon.
It extends on the surface of an entire lot, 17 meters by 35, typically occupied by two dwellings. The house of the dragon was bisected by a long divider wall: to the north the reception area, to the south the residential area. The entrance led into a narrow corridor which gave access to a large courtyard, carefully paved with black and white earthenware tiles arranged to form stripes of alternating color. Around the courtyard ran a portico (pastás), which housed on its west side three banquet halls with convivial couches, two of them boasting mosaic floors.
The mosaic of the dragon decorated the threshold of one of these rooms, further embellished inside by a white mosaic carpet bordered by a stripe of black basalt tiles.
