 Collectively, the ruins are called Qal'a-e Kafaran "Fort of Infidels" or Qal'a-e Sam "Fort of Sam," the grandfather of the mythical Rostam (one of the fortresses here is named "Rostams castle").Both names reflect pre-Islamic heritage.The walls of the temple were once extravagantly decorated with murals, some of which are now on display in museums in Tehran, Berlin, New Delhi and New York.
