The province of west Azerbaijan hosts the biggest educational, religious and social center of Iranian people before the advent of Islam. UNESCO world heritage site called Takht- e Soleyman temple lies in an eye catching valley set on a glorious volcanic mountain. The historical temple was used by Zoroastrians as their principal sanctuary. Some renovations were applied to the site during Ilkhanid Period in 13th century. Sassanid Dynasty also dedicated a temple to Anahita during 6th and 7th Centuries. This monument was named according to Semitic style after the Arab Invasion. In ancient times, three Royal fires or Great fires were kept in the temple, the fires which were upon the order of Sassanid rulers were planned to ascend the throne.
