Istanbul, Turkey is an awesome city filled with vibrant colors and a dynamic culture and history. We used a Professional Tour Guide from Constantinople Guide (Ozkan Bicer) and it was a perfect way to learn about the city and see all the amazing sites! I thought it was so neat to learn that part of Istanbul was in Europe and the other part of Istanbul was in Asia. It was established around 660 BCE and was called Byzantium, Constantinople, and New Rome throughout history and was the imperial capital for the Roman, Byzantine, Latin, and Ottoman Empires.

You can really wear almost anything, but it is better to dress conservatively covering shoulders and knees. You cannot go into mosques with your knees exposed - but they do have skirts and shawls you can put on at the entrance to most places.
