Mosques: Blue Mosque & Aga Sofia
Museums: Istanbul Modern
One of their current exhibitions is a photography collection called “On the Road: Images of Turkey from the Nar Photos Archive” that documents current events in Turkey – political, social, lifestyle – in unique, thought-provoking ways. I wasn’t allowed to take any photos in that room, but some of the prints were extremely powerful.
Some other museums to check out (that I would have visited with more time) include the Istanbul Archeology Museum and the Turkish and Islamic Arts Museum.
