Semnan Province


Semnan, like many other Iranian cities, has gone through many ups and downs. In the passage of time it has witnessed many historic events, from the prehistoric times up to its invasion by Koorosh; from the capture by the Muslim army, to the invasion by the Turks of Ghaznavid; from the destructive invasion by the Mongols, to the deadly onslaught of Teymour Lang (Tamerlane) … It has also often experienced uprisings against oppressive rulers.Today, the city of Semnan covers an area of 19,991km, and is 1,130m above the sea level, at a distance of 228km from Tehran.

As bayazid Bastami, that great mystic, has said: “I went to the countryside and found it wet because of the rain of love that had poured on it. One’s foot would sink into love as it would into snow”.
