The city is a whole with its local, cultural, social dynamics, and built environment. From economics to socio-political, and contextual relations, it contains different kinds of topological relations. In time, these relations become hybrid layersin different ways; and play a decisive role in the change and transformation of theurban context. Therefore, the ‘palimpsest’ is an important notion that reveals thecausalities and the relations behind the transformation of an urban context; anda palimpsest urban reading helps us to recognize and understand the dynamicrelations of urban transformation by making an inquiry for the physical and con-textual values. Through its layers, an urban palimpsest reading makes it possibleto observe these characteristic changes and actors involved in changes.Extending from The Golden Horn to The Marmara Sea, Istanbul Land Wallscan be regarded as one of the distinct examples of the urban palimpsest. Sinceits construction, Istanbul Land Walls have been functioned differently from timeto time; and played a critical role in macro-scale and mezzo-scale changes in theurban context. Today, besides showing the patterns of previous civilizations, thesebuildings also show the traces of a contextual transformation, a transformationfrom being borders to becoming boundaries. The study discusses the land wallsand their impact on the hybridization of the urban context through a historicresearch, current observation, and photographs in the direction of Topkapı-Yedikule Gates.
