The Hamburg Neustadt Centre occupies the second and third floor of an eight-storey glass building in the ‘new town’ district of the city. It is within easy reach of both rail and U-Bahn metro system stations. Hamburg is the third largest port in Europe and although it is based on the River Elbe, it is considered a seaport because of its ability to handle ocean-going vessels. It is an important location for the civil aerospace industry and other engineering and manufacturing sectors, as well as more hi-tech companies. Hamburg is home to many leading niche companies, and research and development expertise through institutions like the Hamburg-Harburg University of Technology. The renewable energy sector is developing rapidly, with cutting edge technologies emerging from the region.
