istanbul is a melting pot of cultures and also the secret and unofficial capital of Turkey. After almost two thousand years of domination, Roman emperors and Ottoman sultans left behind impressive buildings that the visitors can discover even today. Worldwide famous domes and towers rises magically from Istanbul to the sky. The Bosphorus, which cuts through the city on the Bosporus, forms the natural border between Europe and Asia. As the economic centre of the Turkish Republic, Istanbul is more than just a historical city with a never-ending chain of cargo and passenger ships on the Bosporus, and an endless stream of cars that will make their way on an adventurous journey through the streets. A few kilometres away from the hustle and bustle, wide forests provide rest and relaxation and beaches offer swimming opportunities. The number of museums, churches, palaces, mosques, bazaars and sights seems endless - Istanbul is one of the most fascinating cities in the world.
