The city is the library of different social backgrounds. One can recognize this, especially by the dialects throughout the city. To get to know the city you should wander around the streets. The architectural heritage reflects the culture and life style of Istanbul.İstanbul was built by the Romans, both the Byzantines and the Ottomans revitalized the city, building magnificent domes, which are the symbols of the city. Some of the historic sights were destroyed by earthquakes and some by human beings. However, those who fall in love with Istanbul do not only pick its roses but plant new ones. We try to make Istanbul survive by protecting its cultural heritage. You too can contribute by living here.This book includes pictures of monuments from the Byzantine Era. The postcards reflect the era of 19th to the beginning of 20th centuries which proves how Byzantine Constantinople survived under Ottoman tolerance. Looking through the pages will take you back to 100 - 150 years of nostalgia. I strongly suggest that after reviewing this book the reader should rediscover the monuments in each corner of the city where the heartbeat of istanbul can be felt.1 invite you to explore Istanbul to discover the traces of the Roman, Byzantine and Ottoman Empires, all in the same landscape.
