When the model was made, the Nicolaiviertel (yellow, center) had just been reconstructed. this was a major milestone for the festivities of 750 years Berlin in 1987. The reconstruction of Nicolaiviertel marks a turn in urban planning from the mega-buildings and spaces as seen on Fischerinsel in front, towards a more human scale. a similar change of planning culture appeared in most European countries around that time. An example is the battle for the Nieuwmarkt quarter in the centre of Amsterdam, in the late seventies. Quite a few buildings have dissappeared since. <a href="http://www.stadtentwicklung.berlin.de/planen/stadtmodelle/de/ausstellung.shtml" rel="nofollow">Ausstellung Stadtmodelle Senatsverwaltung für Stadtentwicklung Am Köllnischen Park 3</a>
