The township of Koohdasht (Kuhdasht) is located to the west of LORESTAN province. Archaeological studies in areas such as Sorkhdam, Lori, Hamiyan and Sartarhan have revealed that Koohdasht was one of the centers of civilization of ancient Iran. The discovery of an Assyrian temple shows that this area was inhabited even before the first millennium BC. The historian Mostowfi has also mentioned Koohdasht and Tehran in his records, and that these were extinct areas, centuries before the Arab invasion.
Kuhdasht is a large plain which is surrounded by mountains. In Persian, Kuhdasht is composed of "Kuh," which means mountain, and "Dasht," which means plain. Kuhdasht was the residence of Kassites, one of the ancient peoples of Zagros Mountains. There are some antique pieces of bronze in Louvre museum from Kassite civilization.
