The subject of the research is the analysis of urban development of the Bratislava Petrzalka territory which is in close connection to the border with Austria. The research summarizes the progress and presents various western visions of the urban development. The paper presents, by virtue of an analysis of several urban schemes, the changes of development of Bratislava on the right bank of the Danube River with a special emphasis on the border area. This scientific study is the first specific overall view on urban development of the area in the 20th century. The analysis covers five periods of development: 1st - the time until 1918, 2nd the period from 1918 until 1939, 3rd the period from 1939 until 1945, 4th the period from 1945 until 1989, and 5th the period from 1989 up to today. During each of these periods, the state border between two countries, as an important determinant of spatial development of Bratislava, had a different political character. The area has gone through various transformations - from the common territory through the "Iron Curtain" up to the current state. The analysis of first proposals of this territory's urban development (a plan by Paloczy in 1917, a regulation plan contest in Bratislava in 1929 and the first post-war plans in1949) indicates that the plans considered the use of the land on the right bank of the Danube only marginally. It was not before 1963 when a new plan first ' stimulated the development of the south - the area of Petthlka. The so-called Iron Curtain strongly influenced the development and the current condition of the territory in 1948-1989, and disrupted the natural contacts between the settlements. Only after 1989 the western development of Petrzalka could come into consideration. The early planning studies have replaced the Iron Curtain with a green border. Then, PetrZalka only started to think about the possibilities of its western development. Despite this, the remained marks on this territory indicated that there was a basic for reunification of the area. The Austrian border towns have become a part of the Bratislava agglomeration. Today, several urban studies suggest the possibility of mutual development of this area, the development, which may be one of the strongest expressions of the motto "Europe without borders".
