Luxembourg – A divided City ? The historical development of Luxembourg's Kirchberg district as a town within the town.

The capital of the Grand Duchy of Luxembourg is one of the three official seats of the EU, alongside Brussels and Strasbourg. Over the past 40 years, both the Grand Duchy and its capital city have undergone a remarkable trajectory of growth and change.
One of the major sites implicated in this economic success is the Plateau de Kirchberg, a 365-hectares area that now hosts the European and banking district as well as some components of nationally important infrastructure (for example the National Library, Philharmonic Hall and many others).
Initially agricultural land, the Kirchberg was developed by the central government from the early 1960s. It was then mainly designed in the fashion of a modern office town, with high-rises, starchitecture and wide boulevards. With its emblematic appeal of modern town planning, Kirchberg presents a huge contrast to the old city wiith its more than thousand years of history on the opposite side of the deep-cut Alzette valley.
But can we see a divided city here? Is it not rather an urban extension, though large and of international significance, comparable to areas such as La Défense in Paris or the London Docklands?
The thesis is pursued as to whether the Kirchberg district can be seen, de facto, as a second city.
