Takht-e Foulad is the name of a cemetery in Isfahan that is believed to be the burial place of Joshua, the Jewish prophet. The advent of this cemetery is not clear, but the existing evidence connects it to the pre-Islamic period. A great number of buried celebrities, and valuable historical monuments have made this graveyard as an important cultural and historical site. It had been a gathering place for Dervishes to celebrate their ceremonies before Safavid dynasty. A Khanqah was also constructed in the cemetery and was known as Baba Rokneddin. During Safavid dynasty, a caravanserai was constructed beside this cemetery which was the last residential place for the caravans entering Isfahan from the south. Takht-e Foulad was specially designed for burring the authorities during Safavid period, but it became a public cemetery afterward. Takht-e Foulad is a treasure with various artistic works, including architecture, gilding, tile, calligraphy, carving, poetry, painting and drawing from different periods in Isfahan.
