Seleukia-Ktesiphon consisted of two cities, Seleukia on the left and Ktesiphon on the right side of the Tigris. It was the residence of the Parthian and the Sassanidian kings. Together the two cities had a population of 500 000. With the foundation of Baghdad in the 8th cent AD the city lost its importance.
The last remains of Ktesiphon is the great arch of Taq-i-Kisra ("Arch of Chosrau") (Sassanid, 7-8th cent?). The technology of erecting large arches over square or rectangular bases seems to have come with the Parthians from Khorassan. The Romans only knew how to erect copulas on circular tambours. The "Iranian" cupola using spherical Pendentives reached Byzantium in the 6th cent (Aghia Sofia) and Western Europe only in the Renaissance (Brunelleschi's dome in Florence). See also Bukhara.
