History
Historians have recorded Espahan, Sepahan or Isfahan initially as a defense and military base. The security and protection of the gradually increasing castles and fortifications, thereby, would provide the protection of residents nearby, therefore leading to the growth of large settlements nearby. These historical castles were Atashgah, Sarooyieh, Tabarok, Kohan Dej, and Gard Dej. The oldest of these is Ghal'eh Sefeed and the grounds at Tamijan from prehistoric times. The historic village of Abyaneh, a nationwide attraction, also has Sasanian ruins and fire temples among other historical relics.
During the 17th and 18th centuries, Isfahan province enjoyed high standards of prosperity as it became the capital of Safavid Iran. While the city of Sepahan (Esfahan) was their seat of monarchical, Kashan was their place of vacation and leisure.
