Istanbul.

We then walked to the Blue mosque, called that because of the blue Iznik tiles inside. We did not go inside because we were wearing shorts and it is disrespectful to Islam. Many other people went in in shorts and sleeveless tops which I don't think is the right thing to do! Outside the Blue Mosque there were two Egyptian obelisks that were put there in 360AD! So they are old and have been in Istanbul for a long time!
