Ortakoy Mosque - one of the main Istanbul landmarks.
In the background part of the Bosphorus bridge can be seen. It's the worls fourth-largest bridge. Built in 1973, it's the first of the two bridges connecting Europe and Asia.
Photo taken from moving boat in the Bosphorus strait. It was raining just few minutes before, but then sky started to clear, and the Mosque became very well lit by the sun.
