Suleymaniye Mosque, Istanbul
Built between 1550 and 1558 the Suleymaniye Mosque is the second largest in Istanbul. If you are returning to Istanbul on one of the ferries the mosque dominates the skyline by the ferry terminal and Galata Bridge. This was my view one evening, arriving on the ferry from Harem.
