Ṭāq-e Bostān

Ṭāq-e Bostān, village in western Iran, just northeast of Kermānshāh city. It is known for its rock carvings (bas-reliefs) of Sāsānid origin (3rd to 7th century ad). The carvings, some of the finest and best-preserved examples of Persian sculpture under the Sāsānians, include representations of the investitures of Ardashīr II (reigned ad 379–383) and of Shāpūr III (383–388), the latter in a man-made cave carved in the form of an iwan (three-sided, barrel-vaulted hall, open at one end).
