Quick Summary

The Palace of Shāpūr I, also known as Taq Kisra, is a significant architectural remnant located in Ctesiphon, Iraq. This structure is famous for its massive, single-span brick arch, one of the largest in the world. While traditionally attributed to the Sasanian king Khosrow I, Shāpūr I also contributed to the site during his reign from 241 to 272 CE. Ctesiphon served as the winter capital for both the Parthian and Sasanian empires. The city was eventually superseded by Baghdad and its ruins were used as a source for building materials.1
