Construction of the Commerzbank Tower in 1997 spurred massive concentration skyscrapers in the banking district. The tower, considered oversized at the time, overshadowed a neighboring high-rise, today’s Global Tower, only a few meters away. From the city government’s point of view, the so-called “cluster concept” seemed well received because there was no resistance from the public. This fueled the city’s fundamental openness to high-rise buildings. More towers were built close to one another in the Financial District, also more visually appealing than before, and here and there a tower became open to the public.
The economic boom finally brought a number of new high-rise locations to City West that were easily accessible by car. It was the era of the car-friendly city.
Planning for the European District was inspired by the economic boom and guided by experience from the Financial District. Several skyscrapers were planned in a small area around the Skyline Plaza shopping center.
