One of the largest and oldest covered markets in the world.
What Dennis Callan say about G.B. :
TheGrandBazaar as the world’s oldest and biggest historical Bazaar, was constructed just after the conquer of lstanbul to have an income for Hagia Sophia Museum. At first the Cevahir and Sandal Covered Bazaars (where fabrics or jewels were bought and sold) were in service at this historical Bazaar which was located between Nuruosmaniye and Beyazıt Mosques. Since the day it was opened, it has immediately become the center of shopping like today is.
