Casa Romana, Roman archaeological site in Kos Town, Greece.

Casa Romana is the ruins of a wealthy Roman residential home in Kos Town containing roughly 36 rooms arranged around three courtyards with fountains. The structure displays Roman building methods through columns, porticos, and preserved mosaic floors.

The villa was built in the late 2nd or early 3rd century AD on the ruins of a Hellenistic house that had a drainage system. The 1933 earthquake destroyed much of Kos, and the Italian administration excavated the site; under the archaeologist Luciano Laurenzi the reconstruction was completed by 1940.

The mosaics throughout the rooms display sea creatures like dolphins and water nymphs, showing what wealthy Roman residents found beautiful. You can still see these artworks on the walls and floors today.

The site is easy to reach on foot from the town center and has little shade, so visiting in the morning or late afternoon works best. Sturdy footwear helps when walking over uneven ground between the ruins.

The house features an advanced water drainage system and decorated water tanks built beneath the floor surfaces. This underground network reveals sophisticated Roman knowledge of water management within private homes.
