Shemiran lies in the slopes of Alborz Mountain and enjoys a suitable mild climate. It has fine and well-kept parks and is home to the richest class of Iranian society. Most of the foreign embassies and the Tehran International Fair are situated in Shemiran.
Shemiran used to be the summer residence of the Qajar and Pahlavi Shahs who built several palace complexes and villas in the area. Some examples are the Sa'dabad Palace Complex and the Niavaran Palace Complex.
It is common in the Iranian languages that the letter "z" changes to letter "ch" For example in Persian the word "ruz" or "rooz" (day), from Middle Persian "roch", is still "roch" in Balochi language and "roj" in Kurdish. Another example is the word "zemestan" (winter) consisted of two parts: "zem" (cold) + "estan" or "istan" (being, or existence), which sometimes can be seen in Persian Literature and common usage as "chamestan" or "chemestan".
