Urban fissure: reconceptualization of the land walls within the urban milieu of İstanbul

Baş Bütüner, Funda
The major intention of this thesis is to introduce a new concept –urban fissure- to discuss the positionality and spatiality of city walls within contemporary urban milieus. Besides being an architectural defense structure, covering a considerable amount of land in cities, city walls have always been an important urban component. Land Walls has been a unique example of city walls that have existed for 15 centuries as an untouchable object in a metropolitan city like İstanbul. After the Ottoman Conquest in 1453, Land Walls lost their major defense purpose, and became a part of civilian life. From that time until the mid-20th century they loosely marked the west edge of the city. However, in the second half of the 20th century, with the enormous expansion of İstanbul, Land Walls have remained in the middle of the city. Throughout their history, they have produced a diversity of spaces, uses and traditions. Their unusual structure, and their complex spatiality including spaces adjoining and around them have generated several challenging processes. They have raised uncertainties and sometimes problems not only in spatial terms, but also in regulations and implementations. In this respect, regarding their current positionality and spatiality, this thesis argues Land Walls and walled zone as an urban fissure which is supposed to make them legible within the urban milieu of İstanbul.


City walls of İstanbul: An Analysis of Place-Making in The Urban Context
Akyol, Eda Selin; Cengizkan, Ali; Department of Architecture (2011)
This thesis aims to analyse the İstanbul Historical Peninsula city walls under the framework of place-making. This study focuses on proposing a way of looking for the place identity of walls upon the dialect of the times, and the dialogue of physical configurations and cognitive imaginaries. The present wall front is studied and the frequently repeating patterns on this fabric are pointed out throughout the understanding which incorporates both the geographical and spatial imagination. As the identity of pl...
Urban compactness : a study of Ankara urban form
Çalışkan, Olgu; Günay, Baykan; Urban Design in City and Regional Planning Department (2003)
Sustainable urban development is mentioned together with the concept of urban form in contemporary planning literature. The main reason behind this is a need for determining an ideal physical development scheme and its main principles of urban future in a broad term. Besides, the operational side of urban planning requires a concrete set of design codes in order to transform urban space in both macro and mezzo scale. At this point, the concept of urban compactness and the idea of Compact City have come into...
Growth control at the urban fringe: planning and policy instruments – the case of Ankara
Sınacı, Fulya; Gedikli, Bahar; Department of City and Regional Planning (2016)
Urban growth dynamics play an important role in determining the future scenarios of cities and in the shaping of the urban form. Although spatial growth can be considered as an opportunity to provide new living and working places for growing populations, it is arguable whether all decisions aimed at physical growth are compatible with local dynamics. Even if growth is needed, considering the conditions of a locality, it is not always easy to control this growth and prevent it from turning into sprawl. Previ...
Urban Fissure: The Spatial Manifestation of the İstanbul Land Walls and Mural Zone
Baş Bütüner, Funda (Middle East Technical University, Faculty of Architecture, 2019-01-01)
This article intends to question changing spatiality and position of the "urban edge" in expanding cities, and argues its spatial manifestation as an "urban fissure". The term "edge", which basically refers to the end line between two opposing milieus, became redundant in the expanded urban surface; and necessitates a critical review through a new concept. Edge, demarcating the communication/interaction line between two milieus, acts also as a "productive frontier" and generates an edgescape that subsequent...
Sustainable transport in city-regions:b
Nal, Seda; Babalık, Ela; Department of City and Regional Planning (2008)
While the vast literature on sustainable transport emphasizes certain urban development patterns as those that should be encouraged in urban planning, it is a fact that there is an increasing tendency in many urban areas in the world towards becoming a city-region. However, whether these city-region development patterns can help attain a more sustainable urban growth and transport system is a relatively less studied area in the field of sustainable transport. In general terms, the study aims to bring togeth...
