Istanbul is the largest city in Turkey, it is also the only city in the world which spans two continents with a smaller share of the city being on the European shore of the Bosphorous, whilst the majority is on the Asian shore. The city has a long and fascinating history and in its time has been the capital city of the Roman, Byzantine and Ottaman empires, and all of these have left their mark on Istanbul leaving behind a rich legacy of ancient sites which have made it a Unesco world heritage site. There are so many things to see and do from gentle boat trips down the Bosphorous to cultural excursions to some of these important sites including the impressive Hagia Sophia which was originally a Basilica before being converted into a Mosque, and the lavishly decorated Topkapi palace which was home the the Ottaman Emperors for four centuries. However maybe one of the best things to do is justto wander and let yourself get lost round the massive labyrinth which is the 'Grand Bazaar' and spice markets and gold souks, and breathe in the tastes, sights and smells of this most exotic and exciting of cities.
