Object description

Tāq Kasrā, and Iwan-e Kasrā , meaning Iwan of Chosroes, are names given to the remains of a circa 3rd–6th-century Sasanian-era Persian monument, which is sometimes called the Arch of Ctesiphon. It is located near the modern town of Salman Pak, Iraq. It is the only visible remaining structure of the ancient city of Ctesiphon. The archway is considered a landmark in the history of architecture, and is the largest single-span vault of unreinforced brickwork in the world.
