Ayvalık is an unusual Ottoman town because of its history. In the early-tweentieth century, the town was turkized after being under the influence of Greek population and culture along for approximately two century time. In Greek period in Ayvalık, churches, which are serving as cores, provide the dwellings to grow in their surroundings like in many Christian towns. Analysing the settlements around these churches, it can be seen that the street fabric and building blocks are formed around the churches. The Hamidiye Mosque dated to the late-nineteenth century, and which was built by Sultan Abdülhamid the Second, is a small but symbolically important addition to Ayval›k’s urban structure. This mosque which was built with the impact of the Greek revolution in 1821 seems to have a symbolic attitude embodying the power of the central government rather than serving as a congregational place for the muslim community; the power of imperial capital, taking the rule over, following the mutiny, which came after a period of economical and cultural prosperity provided by the autonomy of a city-state.
