Tolga

Tolga is an oasis of the Ziban, south of the Aurès Mountains. Its palm groves stand out against the dry country surrounding them, and the oasis is renowned for its dates. In the fourteenth century the historian Ibn Khaldun described Tolga as the centre of the western Zab, one of three divisions of the region, alongside Biskra in the centre and Badis in the east. The older settlement also contains stones from the Roman period.
