The Spice Bazaar constructed in the 17th century, is the arasla of Yeni Mosque complex in Eminönü, in Historical Peninsula. It has surrounded by historical buildings such as a mosque, madrasah, tomb, commercial inns. The bazaar has always an extremely rote in the urban history at all times. By accommodating the city as a spice market, always largely spices or similar herbaI products have been sold in the bazaar. Thus, the bazaar has been always a shopping place that people prefer to go on purpose and also being belonged and committed to. Moreover, as apart of daily urban Iife, the bazaar is a welcoming point in Istanbul. Its large "L" block characterizes the Eminönü square in the view of Galata Bridge. But nowadays, the bazaar building is threatened by some adverse effects such as new additions closing its main façade, gift shops beginning to take herb and spice sellers' places and also underground roads that make it only a crossing point. Unfortunately these troubles cause the lack of relation with other historical heritages and the unhealthiness of the historical district. Only if, it would have better eonditions on the purpose of use and been increased the environmental life qualities, Egyptian Bazaar could have enriched the urban Iife. On the other hand, the building's urban life quality can be increased by noticing the value of the building physically, socially, economically, culturally and architecturally. Therefore, it must be succeeded that bazaar's and also historical heritage's sustainability by saving its original function as a spice bazaar.
