Two Competing Visions for the Capital City of the Turkish Republic: Léon Jausseley’s and Hermann Jansen’s Planning Proposals for Ankara (1928)

The diffusion of the city planning practice took place often by the initiative of local actors, and was enabled by the collaboration of international experts in the early 20th century. In the newly founded Republic of Turkey, “international experts” were invited to develop city plans in conformity with the principles of the new “science of town building.” A planning competition was organized for the construction of the new capital Ankara in 1927. Three planners from France and Germany, Léon Jaussely, Hermann Jansen and Leon Brix were invited to prepare their plans for the future capital city. Jansen’s and Jaussely’s proposals reflected a similar understanding influenced from the Garden City model, while they differed in their approach to the old town and the representation of public spaces. Jaussely’s plan that reflected the traits of French Beaux-Arts urbanisme brought a zoning on the basis of neighborhood units with different building typologies. He developed a “système des parcs” formed of a network of green boulevards superposed on the transportation infrastructure. Jansen proposed also a system of continuous green corridors -a network of “freiflächen” that connected the neighborhood units destined to different socio-economic groups. Yet, the attitudes of the two experts vis-à-vis the old town were fundamentally different. While Jaussely proposed to intervene radically on the historical town by opening new avenues and squares, Jansen preserved the historical urban core around the citadel, that he called “the crown of the city.” The local jury found Jansen’s entry more suitable to the “national character” and more applicable. Finally Jansen was given the commission to prepare the implementation plans of the city. The present paper compares various aspects of the two proposals for the new capital city by Jaussely and Jansen, and inquires into the way they were received by the local actors.

Planning As A Tool For Modernization In Turkey: The Case Of Hermann Jansen’s Plan For Mersin
Beyhan, Burak; Uğuz, Selçuk (Middle East Technical University, Faculty of Architecture, 2012-12-1)
Early 20th century urban development plans and regulations as the culmination of the efforts made for the modernization of the cities constitute a special and substantive domain of focus for the historical analysis of cities in terms of understanding the nature and objectives of planning today. Yet, except for big cities such as Ankara, İstanbul, İzmir, Adana and Bursa, most of the cities in Turkey are not studied in depth within such a context. Unfortunately, those studies conducted for both big and small ...
A Sub-utopian Landscape from the 20th Century: A Comparative and Critical Analysis of the Forest Farm ‘Dream’ of Ataturk.
Güneri Söğüt, Gizem Deniz (2019-11-15)
Even though the 20th century architecture and urbanism have been very frequently visited for utopias, utopian landscapes in specific have remained underdiscussed. The histories and narratives of landscapes, however, can never be fully isolated from those of utopian thought. This work dwells on various modes of 20th century landscape utopianisms through a comparative and critical reading of Ataturk Forest Farm, in Ankara. Ataturk Forest Farm is one of the most significant spatial projects which had been real...
Resolving the historic urban tissue by tracing the changes as a basis for its conservation : Samsun from 20th century until today
Yazıcı, Merve; Bilgin Altınöz, Ayşe Güliz; Restoration in Department of Architecture (2013)
This thesis identifies the causes and the process of the change of the historic city center of Samsun since the beginning of the 20th century by the role of the development and conservation activities. Because of rapid urban growth and the lack of conservation principles in city plans, most of the city centers have been subjected to growth-conservation contradiction. As a result of this, the historic city centers lose their unique characteristics and cultural heritage while they change rapidly. The city of ...
