Covering the area between Konak Square and the Agora of Smyrna, Kemeraltı Bazaar is a part of İzmir where residential buildings are practically absent and which consists, not on only of hundreds of commercial establishments but also of numerous religious buildings (historic mosques and synagogues) concentrated in walking distance from each other. İzmir center's two largest churches, a Catholic church dedicated to Polycarp and the Greek Orthodox church of "Aya Vukla", premises of the archaeological museum until recently and currently in phase of being restored, are also located slightly outside Kemeraltı zone. The entire area corresponds to İzmir's small inner bay which existed until the 18th century and is thus land gained from the sea. 1590-built Hisar Mosque and the 1744-built Kızlarağası led the pace for the establishment of a commercial zone here which is still marked by many buildings of İzmir's Ottoman period.
