Ctesiphon

Ctesiphon was an ancient city located near the Tigris River in modern-day Iraq. It served as the capital of the Parthian Empire and later the Sassanian Empire, making it a significant cultural and political center from the 2nd century BCE until the 7th century CE. Known for its impressive architecture, including the grand palaces and the famous Taq Kasra arch, Ctesiphon was a hub for trade and learning. Its strategic location allowed it to flourish before being conquered by Arab forces, leading to its decline. Today, its ruins remain an important archaeological site.
