Siluet of Istanbul
This photo shows the siluet of Istanbul, the beautiful Hagia Sophia (on the right) and the Blue Mosque (on the left). Like the Statue of Liberty in New York, and the Eifell Tower of Paris, everybody is looking for Hagia Sophia in Istanbul which was selected as the symbol of the city.
It is the most beautiful architecture which reflects the past of the city. It is well protected where you may see elements from both Christian and Muslim culture together.
You may find more about Hagia Sophia under that post.
