The city of Seoul in its historic continuity develops extreme examples of designing open city surfaces, especially parks, streets and plazas. In the 1960s, due to rapid economic development, Seoul experienced drastic changes at the urban level, and found itself in a phase of exceptional growth - a rapid economic boom was accompanied by a high rate of industrialization and rapid urbanization. The paper will present the chronology, genesis and basic characteristics of the most significant landscape architecture projects in the process of Seoul's development. This work will examine and present certain philosophies and directions to which the projects presented in this work belonged, and discuss how modern urban planning and technology have great potential for undoing the damage caused by industrial growth based on literary sources and field observations, and a selection of the most relevant urban projects whose features show positive trends in arrangement and/or design and adequate maintenance. A structural and value analysis of the existing spatial and landscape characteristics of selected examples will be presented. The basic evaluation criteria will cover the design, ambient and functional features of the locations with an analysis of the results that each project achieved in a certain area. It is concluded that the adoption of new western approaches in designing around the year 2000, well suited the ideas of architects and the needs of the Korean people as such. When the movements gained momentum, they tried to restore older urban forms like the traditional madang (inner courtyard) and alleyways as part of the new approach. Since the fundamental principles of viewing indoor and outdoor spaces as continuous wholes, architects can confirm the possibility that the specific tradition of Korean architecture can develop into its more universal, globalized version through the adoption of new, more progressive approaches.
