The Iranian booth is a mystery to me: First, the pillars at the entrance show the numbers 2001, but I couldn't find out what this means. Like many other booths I couldn't make out any exhibits relating to the EXPO theme Human-Nature-Technology. Just plenty of history in pictures and a quite interesting film in the film theatre of the large booth.
The second part of the booth located across the aisle mainly presents carpets: Since it was close to closing time, it was difficult to explore the area. Taking everything into consideration, I really didn't get the meaning of the Iranian booth.
