El relleu de la victòria de Sapor I, Bishapur

Bishapur or Bishâpûr (Persian: بیشاپور‎) was an ancient city in Persia on the ancient road between Persis and Elam. The road linked the Sassanid capitals Istakhr (very close to Persepolis) and Ctesiphon. It is located south of modern Faliyan in the Kazerun County of Fars 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 Sassanian Empire or Sassanid Persian Empire (/sæˈseɪniən/ or /ˈsæsənɪd/; also spelled Sasanid or Sasanian), known to its inhabitants as Ērānshahr and Ērān in Middle Persian and resulting in the New Persian terms Iranshahr and Iran, was the last pre-Islamic Iranian Empire, ruled by the Sasanian Dynasty from 224 CE to 651 CE. The Sassanid Empire, which succeeded the Parthian Empire, was recognized as one of the main powers in Western and Central Asia, alongside the Roman-Byzantine Empire, for a period of more than 400 years.
