Istanbul is the only city in the world which is situated on two continents. In its long history, Istanbul (Constantinople) served as the capital city of the Roman Empire, the Byzantine Empire, the Latin Empire and the Ottoman Empire. During our city tour, we will see the beautiful and very famous Hagia Sophia and Blue Mosque. We will also see the Topkapi Palace, where the personal belongings of the Prophet Mohammed and the earliest Caliphs who followed him are today preserved. There is a chance to visit the Grand Bazaar, one of the largest covered markets in the world with more than 58 streets, 4000 shops, and 250,000 - 400,000 visitors daily, well known for its jewellery, pottery, spice and carpet shops.
