Baghdad: The Arch of Ctesiphon, also known as Taq Kasra, is one of Iraq’s most prominent historical monuments. Located in the area of Mada’in, south of Baghdad, the monument dates back to the sixth century AD, during the reign of Sasanian King Khosrow I Anushirvan.

According to Iraqi News Agency, the arch is distinguished by its massive brick vault, while its throne hall represents a remarkable example of ancient architectural engineering. Its vaulted ceiling was constructed in an arched form without the use of central supports during construction, making it one of the outstanding engineering achievements of its era.

The iwan was an important landmark of the Sasanian Empire and was adorned with mosaics and decorative elements. It formed part of the royal palace complex in Ctesiphon, the capital of the Sasanian Empire.

Today, the arch is the most prominent surviving structure of the Sasanian palace complex at Ctesiphon. It stands as an important testament to the development of construction and architectural techniques in Iraq, as well as to the cultural and civilizational significance the city held in ancient times.

Over the centuries, the monument has been exposed to various factors that have damaged parts of the structure. Efforts to preserve and maintain it continue, given its status as one of Iraq’s most prominent archaeological landmarks.
