I could hear the predawn call to prayer broadcast from minarets across the city as I climbed the stairs to my hotel’s rooftop. From there I enjoyed a magnificent view of the ancient city of Istanbul. Immediately below me, roughly facing north, was Sultanahmet Square, the city’s historic center, flanked by the Blue Mosque to the left and the Hagia Sophia to the right. Behind and to my right I could see the Sea of Marmara and Asia, while in the distance to the northeast I could see the Strait of Bosphorus. As I stood alone on the rooftop in this city of 14 million people, admiring the view all around, it occurred to me I should get out my camera and take some pictures.
