Welcome to Iran

I've just returned from a short vacation in Iran. During the few weeks I took a lot of photos which I'm going to start posting in the upcoming days. Most of them will be the ones I took during the two days that I was in Isfahan, a central Iranian city famous for its architectural beauty. I hope you find this series as exciting as I do. To start it off, here's one from the Jaame' Mosque in Isfahan, which is one of the oldest mosques in Iran. I'm knocking on the huge doors of the prayer hall.
