Damghan and Semnan
Damghan and Semnan are both located in the province of Semnan, a neighbouring province to Tehran towards the east. Damghan is today mainly famous for its pistachios, but it used to be a significant city in the middle ages. Its famous mosque, Tari-Khane, probably the oldest known mosque in Iran, still stands today, and dates back to the 9th century. Semnan, the capital of the province, is also worth visiting and has great recreational, cultural and historic value.
Partitioned between the provinces of Khorasan, Semnan, Tehran, Esfahan and Yazd, the Kavir Desert (meaning 'the desert of salt marsh') is a great salt desert lying in the middle of the Iranian plateau, with a surface area of around 80,000 square kilometres.
