Built in the early 1600s, the Sultan Ahmed Mosque is one of the world's most impressive monuments. Also known as the Blue Mosque for the blue tiles adorning the interior, the tourist area inside the mosque is a peaceful place to linger.

For great views of the city as well as the chance to watch dozens of locals fishing and strolling, take a walk together across the Galata Bridge spanning the Bosphorus Strait.
