Tehran Province :
The modern powerhouse of the government and its engineers, Tehran (meaning warm slope) was originally a village on the suburb of Ray, Iranian capital until Mongol invasion of the country in 1220 AD, when it population moved to the present site of Tehran.  

Transportation:
Basically there are 4 general transportation modes that could take one to get around in Tehran: bus, train (Metro), taxi, and phone taxi. We highly recommend to travel by phone taxi as it is the most economical way, finally. Tehran Metro has two lines: West-Center and North-South. Unfortunately, there is no destination around the conference venue, but if you want to travel to the center of Tehran, Metro is a very good choice as it avoids all traffic jams on the streets.
