Tabas lies in a desert like terrain to the northwest of the province. In the higher regions it experiences a temperate climate, whereas in the plains it is hot. Tabas is 1,345 km. from Tehran. It has been subjected to upheavals and attacks such as the Ottomans and then was occupied by the Esmailieh (a religious sect). During the reign of the Saljuqian, the Esmailieh fortresses were attacked. In the time of Shah Abbas I this city was ruined by the Ozbaks. Many of the historical features remaining there relate to the 5th and 9th century AH.
