The capital of Kermanshah province is mostly populated by Kurds who speak their language and observe their traditions. The historic Kermanshah, which dates back to the 4th century AD, was situated close to the present town. Most of the places of interest are scattered outside Kermanshah and include: “Bisotun”, rock carvings, and inscriptions of Darius I, about 50 m above the ground on the Bisotun cliff. A series of reliefs and inscriptions at Tagh-e Bostan, the only Sassanian rock carvings outside Fars Province.
