The lavish Golestan Palace is a masterpiece of the Qajar era, embodying the successful integration of earlier Persian crafts and architecture with Western influences. The walled Palace, one of the oldest groups of buildings in Teheran, became the seat of government of the Qajar family, which came into power in 1779 and made Teheran the capital of the country. http://whc.unesco.org/en/list/1422
