Having been the capital city of many civilizations throughout a history of centuries, İstanbul is still in the state of the capital city of Turkey, though unofficially. This giant city with a population of twenty million still continues to host countless different cultures. You will say hello to İstanbul, with the unique beauty of its Bosphorus, and you will immediately enter into a vast world. Such a richness has that world! The ageless traces of the Byzantine Empire, unmatched monuments from the era of the Ottoman Empire, palaces, markets… While you walk around the historical peninsula, the Hagia Sophia will rise on the one side and the Blue Mosque on the other. Another day you will visit Topkapı Palace and discover the Grand Bazaar where you will meet the wealth carried along the Silk Road and the Spice Route.
