Istanbul / Turkey
Istanbul, the Turkish metropolis on the Bosporus, is an incredibly versatile and fascinating city, already by the very fact that it is located on two continents. The port goes back to the 17th century and was at that time the center of the city. It is still the most important port of Turkey. The city pollution is unfortunately difficult to control, but Istanbul still has more than enough charming aspects.
It is hardly possible to describe Istanbul in words or list only a portion of the most interesting buildings. The famous Hagia Sophia is certainly the symbol of the city. Otherwise, there is an old hippodrome, some former sultan palaces, the old country wall, bazaars, baths and towers. For a stay of a few hours you best visit only a quarter, explores the different architectural styles and costs the really excellent Istanbul food. Take your time and try more likely to deal in depth with the individual elements of the city than to superficially rush through them. You will love the city.
