Historic and modern, European and Asian ? that's Istanbul. The city at the junction of two continents is home to ancient structures like the Hagia Sophia and the Blue Mosque in the Old City, as well as modern businesses, hotels, restaurants and nightlife in the New City. The sight of mosques and bustling bazaars and the smell of incense and spices are common in Istanbul. Across the Bosporus Strait, the Asian side of Istanbul offers a glimpse into everyday, residential life.
