Tappeh Mill - one of Iran's oldest temples
One of the oldest Zoroastrian temples of Iran - Tappeh Mill (literally - a mill hill), also known as the Bahram fire temple - sits majestically on the hill near Ghal'eh Noe Village not far from the city of Rey. It was named 'Mil Hill' due to the distant similarity of the two main structures with the mill.
Archaeologists say that the temple was built during the Sassanid Dynasty (224 to 651 AD), but it is not possible to find out the exact time of its foundation. This is the reason why scientists cannot establish which Zoroastrian temple in Iran is the most ancient - perhaps it's the Bahram temple. One way or another, there is an opinion that it was built even earlier - during the Achaemenid Empire (550 BC–330 BC), and was destroyed during Alexander the Great's conquest of Iran.
The Zoroastrian temple is a place to keep sacred fire, which as attended by Zoroastrians wearing white clothes - a sign of their ritual purity. During the reign of the Sassanid Empire, Zoroastrianism became the state religion, as a result of which the number of such temples in Iran increased significantly. However, after the advent of Islam, Zoroastrian temples fell into decay.
The temple is built of brick, clay and egg white mortar. There was a large hall with columns inside, divided into three parts. The sacred fireplace burnt in the eastern part of the temple with high vault (iwan) and four round columns. After more than a thousand years, geometrically patterned plaster reliefs, reliefs with floral and animal motifs still can be seen on the walls of the temple. Such a choice of images was dictated by the traditional design of Zoroastrian temples of those times.
Despite the presence of protective structures, the temple was somewhat damaged due to strong winds in 2017. The temple was closed for reconstruction, and now it is - renewed and restored - ready to meet tourists again.
