Warsaw, the capital of Poland, is developing into an important metropolis of Central Europe. With approx. 1.7 million inhabitants, Warsaw is one of the biggest cities and an important centre for traffic, economy and trade in Central and Eastern Europe, and within the European Union (Fig. 1). Warsaw is the principal focus of investment in Poland and of great political and cultural significance.
The cityscape is characterized by the historic old town, by landmarks such as the Culture and Convention Centre and above all by the River Vistula which runs right through Warsaw and divides the city in a natural way.
