Ténès is an ancient town which existed in the 8th century BC. It was called Kartenas at that time. Ténès or Kartenas was first a Phoenician town then it was dominated by the Romans in the last years of the 1st century B-C.They called it Cartennae colonia,They occupied the city for about five centuries.

Later the town was conquered by the Arabs who preached Islam in North Africa. Under the Arab rule, Ténès was an independent monarchy. The Sultan Hamid El Abd was the last ruler of the monarchy of Ténès. The Ottomans attacked Ténès and defeated its army and annexed it to their vast empire in 1512. From that time Ténès lost its fame and importance and became an isolated town. Ténès Al-Atika (Vieux-Ténès-[the lighthouse of sufism][1]) was built by the Moors who escaped from Spanish persecution in the 15th century after the collapse of the Arab States in Spain. In 1843, Ténès was occupied by the French who declared it a township and rebuilt the ancient Cartennae some 2 km to the north of Ténès-al-Atika.
