Today, Istanbul still remains the commercial, historical and cultural centre of Turkey, and its beauty lies in its ability to embrace its contradictions. Ancient and modern, religious and secular, Asia and Europe, mystical and earthly all co-exist here.
Geographically Istanbul is divided into three by water. The European and Asian parts are dissected by the Bosphorus. The European section is further divided into two, as the Old and the New cities, by the Golden Horn. The concepts of old and new are relative only. As the New City was largely reshaped in the Republican Period, it still carries the main urban characteristics of Byzantium. The skyline of Istanbul is shaped by the domes and minarets of over 400 mosques concentrated mostly in the 'Old City' or 'Historical Peninsula' on one hand, and by skyscapers of the 'New City' on the other.
