The city of Vienna is an example of a dense, historically developed city, that expanded outwards from the city centre as the population and the demand for space increased. There is, however, one area that was not included in this otherwise uniform development: The area on the left side of the Danube known as Transdanubia. The river, which in its unregulated state was a wide floodplain dividing the landscape of Vienna into two parts, was a natural border that the growth of the city could not overcome for the longest time. Even until the 19th century, the polycentric network of different streets and villages in this area was still very rural in nature until regulation measures of the river were undertaken and several new bridges were constructed. These interventions made Transdanubia a focus point of urban development. The following increasing urbanisation of the settlement structures represents a trend that has been growing even more rapidly – especially alongside traffic axis – since the increasing motorisation in the 1960s. One of the consequences of this shift in the relevance of Transdanubia in the urban context, was a significant change in the population, both in numbers – from only 12 per cent in the 19th century to currently over 30 per cent of Vienna's total population by current area – but also in occupation – away from farmers living off their own land towards workers. In connection with these processes changes in village structures and settlement patterns can be observed. The village cores were densified and transformed, and the surrounding fields were used for new development. The visible and invisible historical developments, which are spatial, social, political and technological in nature, have a strong influence on the development of the city, they manifest themselves physically in the city and their traces are still evident today. This contribution aims to comprehensively examine these transformation processes in the context of Vienna's Transdanubia.
