Youks-les-Bains was the French colonial name of modern Hammamet, Tébessa.
This was the site of the Ancient Roman city and bishopric of Caesarea in Numidia, which only remains as a Latin Catholic titular see.
In World War II, its Youks-les-Bains Airfield played a part in the allied fight against the Nazi Afrika Korps.
