During the Byzantine period the area of the Grand Bazaar was trade center.After the Turks came to Istanbul,two bedestens which formed the  essence of today`s grand bazaar were built between 1455-1461 by Sultan Mehmet the conqueror in an attemp to enrich the economic life in the city.Later on as people needed more places for their trade , they also added parts outside these bedestens.In the time grand bazaar was formed.

Throughout the Ottoman Period the bazaar underwent earhquakes and fires and was restored several times.

Today,shop selling the same kind of merchandise tend to be congregated in their own street or in hans as this was originally  the Ottoman system.In addition to two bedestens there are also 13 hans in the grand bazaar.

The atmosphere of the Grand Bazaar is very interesting for tourist and has consequenty  become a very popular place for foreign visitors.

It is open during working hours on week days,closing earlier  on Saturdays,while on Sundays and religious holidays it is closed.
