Take in the sights of Istanbul, beginning with the historic Blue Mosque and the Hippodrome, once the heart of imperial Constantinople where chariot races drew roaring crowds. Explore Hagia Sophia with Insight Choice. Choose between the Hagia Sophia History Digital Experience for an immersive journey through the landmark’s layered past or alternatively, visit Hagia Sophia, built in A.D. 537 and famed for its vast dome. Continue to Topkapi Palace, dramatically poised above the Bosphorus and the Golden Horn, then step into the Grand Bazaar, a labyrinth of lanes where centuries-old trading traditions live on in glittering textiles, ceramics and spices. In the evening, join your fellow travellers for dinner at a local restaurant.
