Eywān

Eyvan lies in the western Zagros, amid valleys and wooded hills near the Iraqi plain. The region preserves buildings from the Sasanian age, including the stone vault known as the Arch of Shirin and Farhad. Cut partly into a hillside, its chamber was built from carefully shaped blocks without mortar. Near the Kangir River stands the Siahgol fire temple, a domed structure on four supports, recalling the religious traditions of Iran before the coming of Islam.
