Your day begins with a guided tour exploring the ancient city with highlights to include: the magnificent Topkapi Palace (main residences of Ottoman Sultans), then walk across the Byzantine Hippodrome that was the scene of chariot races. In the afternoon we visit Saint Sophia Basilica, historic seat of the Byzantine church, built in 537 AD and now a museum whose mosaics, stained glass windows and decorated domes have been crafted to create an environment of breath taking beauty. A short walk through gardens takes us to the Blue Mosque of Sultan Ahmet 1 built in 1616 that is famous for unequalled ceramic tiles. Overnight in Istanbul.
