Al Madain Iraq

Al-Mada'in was an ancient metropolis situated on the Tigris in what is now Iraq. It was located between the ancient royal centers of Ctesiphon and Seleucia, and was founded by the Sasanian Empire. The city's name was used by Arabs as a synonym for the Sasanian capital of Ctesiphon, in a tradition that continued after the Arab conquest of Iran.
