Bishapoor,┬á was an ancient city on the ancient road between Persis and Elam in Sasanid Persia. The road linked the Sassanid capitals Estakhr (it is very close to Persepolis) and Ctesiphon. It is located south of modern Faliyan in the Kazerun County of Pars Province, Iran.
Bishapur was built near a river crossing and at the same site there is also a fort with rock-cut reservoirs and a river valley with six Sassanid rock reliefs.
The important point about this city is combination of Roman art and Persian and architectures that we can’t see it before Bishapur construction. Almost all main cities in Persia/Iran had circular shape like old city in Firuzabad or Darab before Bishapour built. Bishapour is the first city with vertical and horizontal streets especially in interior design we can see tile work that’s adapted from Roman Art.
There is an old castle, situated on a steep rock, which is in itself one of the most interesting geological features of the southern Zagros. The oldest monument was relief I, in the Tang-e Chowgan gorge. It shows the celebration of one of Shapur’s earliest victories. Reliefs II and III commemorate the defeat of Valerian. Probably, the small relief VII did the same.
The city, palace, and the so-called Temple of Anahita were built by the Roman POWs. Another monument from the founding period is the cave monument.
The city, surrounded by walls that may have stood some ten meters high, was inhabited by some 50,000 to┬á80,000 people.
Bishapur┬ábecame a center of Islamic learning and there were still people living over here in the tenth century, but the decline had┬ástarted in the seventh century.
