Kermanshah, the capital of Kermanshah Province, is located 525 kilometres (326 miles) from Tehran in the western part of Iran. According to the 2011 census, its population is 851,405. People mostly speak Southern Kurdish. Kermanshah has a moderate and mountainous climate. As one of the oldest centers of civilization, Kermanshah has gained a great importance in the history of Archaeology. One can visit the famous rock Carvings of Bistoon and Taq-e- Bostan near this city. Those at Bistoon celebrate Darius's triumph over the enemies, and those at Taq- e -Bustan mark the revival of rock sculpture in Sassanian time.
The Anahita Temple is the name of one of two archaeological sites in Iran popularly thought to have been attributed to the ancient deity Anahita. The larger and more widely known of the two is located at Kang?var in Kermanshah Province. The other is located at Bishapur. The remains at Kangavar reveal an edifice that is Hellenistic in character, and yet display Persian architectural designs. The plinth's enormous dimensions for example, which measure just over 200m on a side, and its megalithic foundations, which echo Achaemenid stone platforms, "constitute Persian elements". This is thought to be corroborated by the "two lateral stairways that ascend the massive stone platform recalling Achaemenid traditions", particularly that of the Apadana Palace at Persepolis. Another Iranian construction with Hellenistic characteristics is the Khurra mausoleum in Markazi Province.
Bisotun is located along the ancient trade route linking the Iranian high plateau with Mesopotamia and features remains from the prehistoric times to the Median, Achaemenid, Sassanian, and Ilkhanid periods. The principal monument of this archaeological site is the bas-relief and cuneiform inscription ordered by Darius I, The Great, when he rose to the throne of the Persian Empire, 521 BC. The bas-relief portrays Darius holding a bow, as a sign of sovereignty, and treading on the chest of a figure who lies on his back before him. According to legend, the figure represents Gaumata, the Median Magus and pretender to the throne whose assassination led to Darius’s rise to power. Below and around the bas-reliefs, there are ca. 1,200 lines of inscriptions telling the story of the battles Darius waged in 521-520 BC against the governors who attempted to take apart the Empire founded by Cyrus. The inscription is written in three languages. The oldest is an Elamite text referring to legends describing the king and the rebellions. This is followed by a Babylonian version of similar legends. The last phase of the inscription is particularly important, as it is here that Darius introduced for the first time the Old Persian version of his res gestae (things done). This is the only known monumental text of the Achaemenids to document the re-establishment of the Empire by Darius I. It also bears witness to the interchange of influences in the development of monumental art and writing in the region of the Persian Empire. There are also remains from the Median period (8th to 7th centuries B.C.) as well as from the Achaemenid (6th to 4th centuries B.C.) and post-Achaemenid periods.
Every city in Iran is unique in its own way. Kermanshah province since many years ago has been one of the most famous handicrafts centers of Iran. Kak, bread, rice, brown bread and animal fats are the most popular edible handicrafts of this ancient region.
