Abstract
The purpose of this paper is to consider the trend of urban planning in Berlin after World War II. Berlin was called the Laboratory of urban planning in the divided time, and many experimental projects were realized for the center-rebuilding. The analysis is based on the historical and comparative approaches between East and West. The main findings are as follows. 1) Modern Planning from postwar days to the first half of the 1970s led to the opening of the city in both areas. 2) Post-modern planning since the latter half of the 1970s was realized as quite different results between East and West in terms of both the background and practices. While the historical urban restructuring was achieved through IBA Berlin in West-Berlin, in the east side only signs of changing began to appear. This historical background must be an important issue in Berlin after reunification.
