Encompassing the capitals of Austria and Slovakia and their conurbation, the Vienna-Bratislava metropolitan region is one of the focal points of European integration. Divided by a border that until a few years ago was the frontier between East and West Europe, the region faces complex challenges arising from expanding metropolitans and suburbs, superposed by the problem of cross-border integration. The future of Vienna-Bratislava depends on its ability to integrate both parts of the region while ensuring that convergence benefits the whole population.
